+ @section _errors Error Handling
+  HRESULT values are defined by the Microsoft&reg; Win32&reg; API.  For more information, refer to
+  <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/aa378137%28v=vs.85%29.aspx">
+  Interpreting HRESULT Values</a> in MSDN&reg;.
+
+  Note that the S_FALSE return value is considered a non-error value and the
+  SUCCEEDED macro will return TRUE.  S_FALSE is used when there is no failure
+  but there was nothing valid to return, e.g. in IAccessible2::attributes when
+  there are no attributes.  When S_FALSE is returned [out] pointer types should
+  be NULL and [out] longs should generally be 0, but sometimes -1 is used such
+  as IAccessible2::indexInParent, IAccessibleText::caretOffset, and
+  IAccessibleHypertext::hyperlinkIndex.
+
+  Note that for BSTR [out] variables common COM practice is that the server does
+  the SysAllocString and the client does the SysFreeString.  Also note that when
+  NULL is returned there is no need for the client to call SysFreeString.  Please
+  refer to the documentation for each method for more details regarding error handling.
+
+ @section _memory Memory Management
+  The following memory management issues should be considered:
+  @li Although [out] BSTR variables are declared by the client, their space is
+   allocated by the server.  They need to be freed with SysFreeString by the
+   client at end of life; the same is true when BSTRs are used in structs or
+   arrays which are passed to the server.
+  @li If there is no valid [out] BSTR to return, the server should return S_FALSE and
+   assign NULL to the output, e.g. *theOutBSTR = NULL;.
+  @li COM interfaces need to be referenced with AddRef when used and dereferenced
+   with Release at end of life.
+  @li Single [out] longs, HWNDs, booleans, and structs are declared by the caller
+   and passed by reference. The marshaller does all the memory management.
+
+  The following articles may be helpful for understanding memory management issues:
+  @li An article by Don Box in a
+   <a href="http://www.microsoft.com/msj/1196/activex1196.aspx">Q & A section</a>
+   of the November 1996 edition of the Microsoft Systems Journal.
+  @li A posting to a CodeGuru forum,
+   <a href="http://www.codeguru.com/forum/showthread.php?t=364511">Windows SDK
+   String: What are the rules for BSTR allocation and deallocation?</a>
+
+ @subsection _arrayConsideration Special Consideration when using Arrays
+  There are several methods which return arrays.  In the case of IAccessible2::relations
+  and IAccessibleRelation::targets the client must allocate and free the arrays.
+
+  For the remaining methods which return arrays, the server must allocate the array
+  and the client must free the array when no longer needed.  These methods are
+  IAccessible2::extendedStates, IAccessible2::localizedExtendedStates,
+  IAccessible2_2::relationTargetsOfType, IAccessibleAction::keyBinding,
+  IAccessibleHypertext2::hyperlinks, IAccessibleTable::selectedChildren,
+  IAccessibleTable::selectedColumns, IAccessibleTable::selectedRows,
+  IAccessibleTable2::selectedCells, IAccessibleTable2::selectedColumns,
+  IAccessibleTable2::selectedRows, IAccessibleTableCell::columnHeaderCells,
+  and IAccessibleTableCell::rowHeaderCells.
+  For those methods, the server must allocate both the top level array and any storage
+  associated with it, e.g. for BSTRs.  The server must allocate the arrays with
+  CoTaskMemAlloc and any BSTRs with SysAllocString.  The client must use CoTaskMemFree
+  to free the array and any BSTRs must be freed with SysFreeString.
+
+  Also, the IDL for IAccessible2::extendedStates, IAccessible2::localizedExtendedStates,
+  IAccessibleAction::keyBinding, IAccessibleTable::selectedChildren,
+  IAccessibleTable::selectedColumns, and IAccessibleTable::selectedRows includes an
+  extraneous [in] parameter for the caller to specify the max size of the array.
+  This parameter will be ignored by the COM server.
+
+ @section _indexes Zero and One Based Indexes
+  Unless otherwise specified all offsets and indexes are 0 based.
+
+ @section _enumBase Enum Base
+  Note that enums start at 0.
+
+ @section _specialOffsets Special Offsets for use in the IAccessibleText and IAccessibleEditableText Methods
+  IAccessibleText and IAccessibleEditableText can use one or more of the following
+  special offset values.  They are defined in the ::IA2TextSpecialOffsets enum.
+  @li Using ::IA2_TEXT_OFFSET_LENGTH (-1) as an offset in any of the IAccessibleText or
+   IAccessibleEditableText methods is the same as specifying the length of the string.
+  @li Using ::IA2_TEXT_OFFSET_CARET (-2) as an offset for IAccessibleText::textBeforeOffset,
+   IAccessibleText::textAtOffset, and IAccessibleText::textAfterOffset indicates that the
+   text related to the physical location of the caret should be used.  This is needed for
+   applications that consider the character offset of the end of one line (as reached by
+   pressing the End key) the same as the offset of the first character on the next line.
+   Since the same offset is associated with two different lines a special means is needed
+   to fetch text from the line where the caret is physically located.
+
+ @section _discoveringInterfaces Discovery of Interfaces
+  In general AT (Assistive Technology) should try IAccessible2 interfaces, followed by using
+  the MSAA (Microsoft&reg; Active Accessibility&reg;) interfaces.  (In cases where the an application
+  is known to have custom interfaces which provide information not supplied by IAccessible2
+  or MSAA, then those custom interfaces can be used.)  The AT can then, by default, support
+  unknown IAccessible2/MSAA applications, without the application developers having to request
+  AT vendors for support on an individual application by application basis.
+
+  When you have a reference to an IAccessible and require a reference to an IAccessible2 use
+  QueryService as follows:
+  @code
+  // pAcc is a reference to the accessible object's IAccessible interface.
+  IServiceProvider *pService = NULL;
+  hr = pAcc->QueryInterface(IID_IServiceProvider, (void **)&pService);
+  if(SUCCEEDED(hr)) {
+    IAccessible2 *pIA2 = NULL;
+    hr = pService->QueryService(IID_IAccessible, IID_IAccessible2, (void**)&pIA2);
+    if (SUCCEEDED(hr) && pIA2) {
+      // The control supports IAccessible2.
+      // pIA2 is the reference to the accessible object's IAccessible2 interface.
+    }
+  }
+  @endcode
+
+  @section _changingInterfaces Changing between Accessible Interfaces
+  Note that developers must always implement MSAA's IAccessible and, if needed, some
+  of the interfaces in the set of IAccessible2 interfaces.  Although the IAccessible2
+  IDL is coded such that IAccessible2 is a subclass of MSAA's IAccessible, none of
+  MSAA's IAccessible methods are redefined by IAccessible2.
+
+  QueryService must be used to switch from a reference to an MSAA IAccessible interface
+  to another interface.  This has been
+  <a href="http://www.atia.org/files/public/Introducing_IAccessibleEx.doc">
+  documented</a> and the pertinent facts have been extracted below:
+
+  @par
+   Why use QueryService instead of just using QueryInterface to get IAccessibleEx
+   directly? The reason is that since MSAA 2.0, clients don't talk to a server's
+   IAccessible interface directly; instead they talk to an intermediate MSAA-provided
+   wrapper that calls through to the original IAccessible. This wrapper provides services
+   such as implementing IDispatch, supplying information from MSAA 2.0's Dynamic Annotation
+   service, and scaling locations when running on Windows Vista with DPI scaling enabled.
+   QueryService is the supported way to expose additional interfaces from an existing
+   IAccessible and was originally used by MSHTML to expose IHTMLElement objects corresponding
+   to IAccessibles. QueryService is often more convenient for servers to implement than
+   QueryInterface because it does not have the same requirements for preserving object
+   identity or symmetry/transitivity as QueryInterface, so QueryService allows servers to
+   easily implement the interface on the same object or a separate object. The latter is
+   often hard to do with QueryInterface unless the original object supports aggregation.
+
+  Two related references in MSDN&reg; are:
+  @li <a href="http://msdn.microsoft.com/en-us/library/ms696078(VS.85).aspx">
+  "Using QueryService to expose a native object model interface for an IAccessible object"</a>
+  @li <a href="http://msdn.microsoft.com/en-us/library/ms528415.aspx#acc_obj">
+  "Accessing the Internet Explorer Object Associated with an Accessible Object"</a>
+
+  Based on this information from Microsoft, QueryService must be used to switch back and forth
+  between a reference to an MSAA IAccessible interface and any of the IAccessible2 interfaces.
+
+  Regarding switching between any of the IAccessible2 interfaces, applications implementing
+  IAccessible2 should implement the IAccessible2 interfaces on a single object since ATs
+  will be using QueryInterface to switch between the IAccessible2 interfaces.  Implementing
+  the IAccessible2 interfaces on separate objects would require the use of QueryService.
+  There is one exception, IAccessibleApplication can be implemented on a separate object so
+  its common code doesn't have to be included in each accessible object.  ATs should use
+  QueryService to access IAccessibleApplication.
+
+ @section _applicationInfo Access to Information about the Application
+  Servers implementing IAccessible2 should provide access to the IAccessibleApplication
+  interface via QueryService from any object so that ATs can easily determine specific
+  information about the application such as its name or version.
+
+ @section _childIDs Child IDs
+  The IAccessible2 interfaces do not support child IDs, i.e. simple child elements.
+  Full accessible objects must be created for each object that supports IAccessible2.
+  Therefore MSAA's get_accChild should never return a child ID (other than CHILDID_SELF)
+  for an object that implements any of the IAccessible2 interfaces.
+
+  Microsoft's UI Automation specification has the same limitation and this was resolved
+  in the UI Automation Express specification by adding IAccessibleEx::GetObjectForChild
+  and IAccessibleEx::GetIAccessiblePair.  These methods allow mapping back and forth
+  between an IAccessibleEx and an {IAccessible, Child ID} pair.  A future version of
+  IAccessible2 may include similar methods to map back and forth between an IAccessible2
+  and an {IAccessible, Child ID} pair.
+
+ @section _variants VARIANTs
+  Some methods return a VARIANT.  Implementers need to make sure that the return type is
+  specified, i.e. VT_I4, VT_IDISPATCH, etc.  The methods that return VARIANTs are
+  IAccessibleHyperlink::anchor, IAccessibleHyperlink::anchorTarget, IAccessibleValue::currentValue,
+  IAccessibleValue::maximumValue, IAccessibleValue::minimumValue.
+
+ @section _iaaction-iahyperlink IAccessibleHyperlink as subclass of IAccessibleAction
+  In this version of the IDL, IAccessibleHyperlink is a subclass of IAccessibleAction.
+  However, there is no practical need for that inheritance and in some cases, such as
+  an image map of smart tags, it doesn't make sense because such an image map doesn't
+  have actionable objects; it's the secondary smart tags that are actionable.  As a
+  result, implementations should not rely on the inheritance as it may be removed in
+  a later version of the IDL.
+
+ @section _trademark Trademark Attribution
+  The names of actual companies and products mentioned herein may be the trademarks of
+  their respective owners.  In particular, Active Accessibility, Microsoft, MSDN, and Win32
+  are trademarks of the Microsoft group of companies in the U.S.A. and/or other countries.

+
+   The uniqueID is an identifier for this object, is unique within the
+   current window, and remains the same for the lifetime of the accessible
+   object.
+
+   The uniqueID is not related to:
+   - the MSAA objectID which is used by the server to disambiguate between
+   IAccessibles per HWND or
+   - the MSAA childID which is used to disambiguate between children being
+   managed by an IAccessible.
+
+   This value is provided so the AT can have access to a unique runtime persistent
+   identifier even when not handling an event for the object.
+
+   An example of when this value is useful is if the AT wants to build a cache.
+   The AT could cache the uniqueIDs in addition to other data being cached.
+   When an event is fired the AT could map the uniqueID to its internal model.
+   Thus, if there's a REORDER/SHOW/HIDE event the AT knows which part of the
+   internal structure has been invalidated and can refetch just that part.
+
+   This value can also be used by an AT to determine when the current control
+   has changed. If the role is the same for two controls that are adjacent in
+   the tab order, this can be used to detect the new control.
+
+   Another use of this value by an AT is to identify when a grouping object has
+   changed, e.g. when moving from a radio button in one group to a radio button in a
+   different group.
+
+   One means of implementing this would be to create a factory with a 32 bit number
+   generator and a reuse pool.  The number generator would emit numbers starting
+   at 1.  Each time an object's life cycle ended, its number would be saved into a
+   reuse pool.  The number generator would be used whenever the reuse pool was empty.
+
+   Another way to create a unique ID is to generate it from a pointer value, e.g. an
+   object's address. That would be unique because no two active objects can use the
+   same allocated memory space.

+
+   A use case is when a screen reader is grabbing an entire web page on a page load.
+   Without the availability of windowHandle, the AT would have to get the window handle
+   by using WindowFromAccessibleObject on each IAccessible, which is slow because it's
+   implemented by oleacc.dll as a loop which crawls up the ancestor chain and looks for

+/** @brief This interface gives read-only access to text.
+
+ The %IAccessibleText interface should be implemented by all components
+  that present textual information on the display like  buttons,
+  text entry fields, or text portions of the document window.  The interface
+  provides access to the text's content, attributes, and spatial location.
+  However, text can not be modified with this interface.  That is the task
+  of the IAccessibleEditableText interface.
+
+ The text length, i.e. the number of characters in the text, is
+  returned by IAccessibleText::nCharacters. All methods that operate
+  on particular characters (e.g. IAccessibleText::textAtOffset) use character
+  indices from 0 to length-1. All methods that operate on character positions
+  (e.g. IAccessibleText::text) use indices from 0 to length.
+
+ Please note that accessible text does not necessarily support selection.
+  In this case it should behave as if there where no selection.  An empty
+  selection is used for example to express the current cursor position.

+/** @brief This interface represents hyperlinks.
+
+ This interface represents a hyperlink associated with a single substring
+  of text or single non-text object.  Non-text objects can have either a
+  single link or a collection of links such as when the non-text object is
+  an image map.
+
+ Linked objects and anchors are implementation dependent. This interface is derived
+  from IAccessibleAction.  IAccessibleAction::nActions is one greater than the
+  maximum value for the indices used with the methods of this interface.
+
+ Furthermore, the object that implements this interface has to be connected
+  implicitly or explicitly with an object that implements IAccessibleText.
+  IAccessibleHyperlink::startIndex and IAccessibleHyperlink::endIndex are
+  indices with respect to the text exposed by IAccessibleText.
+
+ This interface provides access to a single object which can have multiple actions.
+  An example is an image map which is an image with multiple links each of which is
+  associated with a separate non-overlapping area of the image.  This interface could
+  also be applied to other kinds of objects with multiple actions such as "smart tags"
+  which are objects, typically strings, which have multiple actions such as
+  "Activate URI", "Bookmark URI", etc.
+
+ An interesting use case is an image map where each area is associated with multiple
+  actions, e.g. an image map of smart tags.  In this case you would have to implement
+  two levels of accessible hyperlinks.  The first level hyperlinks would only implement
+  anchor and anchorTarget.  The anchors would all reference the image object.  The
+  anchorTargets would reference the second level accessible hyperlink objects.  None
+  of the IAccessibleAction methods would be implemented on the first level hyperlink
+  objects.  The second level hyperlink objects would implement the IAccessibleAction
+  methods.  Their anchors would also reference the image object and their anchorTargets
+  would reference URLs or the objects that would be activated.
+
+ This use case demonstrates that in some cases there is no need for IAccessibleHyperlink
+  to derive from IAccessibleAction.  As a result it may be removed in a later version of
+  the IDL and it is suggested that implementations should not rely on the inheritance.

+/** @brief This interface gives access to a two-dimensional table.
+
+ Typically all accessible objects that represent cells or cell-clusters of a table
+  will be at the same time children of the table.  In this case IAccessible2::indexInParent
+  will return the child index which then can be used when calling IAccessibleTable::rowIndex
+  and IAccessibleTable::columnIndex.
+
+ However, in some cases that kind of implementation will not be possible.  When
+  the table cells are not direct children of a table, the object representing
+  the cell can define a "table-cell-index" object attribute identifying the 0
+  based table cell index.  This object attribute is obtained by parsing the
+  attribute string returned by IAccessible2::attributes.  The "table-cell-index"
+  attribute can be used just like a child index of the typical case.  ATs should
+  first test for the presence of the "table-cell-index" attribute and if it is not
+  present then IAccessible2::indexInParent can be used as in the typical case
+  where cells are direct children of the table.
+
+ The range of valid coordinates for this interface are implementation dependent.
+  However, that range includes at least the intervals from the first row
+  or column with the index 0 up to the last (but not including) used row or column
+  as returned by IAccessibleTable::nRows and IAccessibleTable::nColumns.
+
+ Note that newer implementations are now using IAccessibleTable2 and IAccessibleTableCell
+  rather than this interface.
