+Contains non-graphical helper code for office applications.
+
+Specifically this module does not depend on or use includes from module
+vcl. Originally all code in svtools that did not depend on vcl was split
+off into this svl ("svtools light") module.
+
+In particular the SfxItemSet is a property-bag like container that
+stores arbitrary sets of properties for everything from text run
+formats, to Chart regression line properties.
+
+There are lots of other useful helpers in here for various office
+tasks; much of this code was originally moved from svx/sfx2.
+
+== Items, Pools and Sets ==
+
+=== SfxPoolItem ===
+
+A small reference counted piece of data.  Many subclasses, each with a
+unique integer to identify its type (WhichId).  Can be compared for equality
+(operator==), Clone()d, and converted to/from uno::Any (QueryValue/PutValue).
+
+A pool item may have value semantics ("poolable"), meaning that
+there will generally be only one instance that compares equal per item pool,
+or not, in which case the item will be Clone()d quite a bit.
+
+=== SfxItemPool ===
+
+Usually there is one item pool per document, with a range of valid WhichIds
+that is specific to the type of document.
+
+The item pool owns all instances of SfxPoolItem or its subclasses that have
+ever been added to an item set.  It also contains a default item for
+every WhichId, which will be (depending on parameters) returned from item
+sets if the set does not contain an item at this WhichId.
+
+=== SfxItemSet ===
+
+The item set can be created with a user-supplied range of WhichIds; it
+will accept SfxPoolItems with matching WhichIds and ignore attempts to
+insert items with non-matching WhichIds.
+
+Items that are successfully inserted into the set will be stored in the
+set's SfxItemPool, and for poolable items only a single instance that
+compares equal under the predicate operator== will be stored in the pool,
+regardless of how many sets contain it, thus conserving memory.
+
+There are members m_pWhichRanges for the valid ranges (as pairs of WhichIds),
+m_nCount for the number of items contained, and m_pItems for the pointers to
+the actual items.

+ * This virtual method allows to get a textual representation of the value

+ * SfxPoolItem subclasses.
+ *
+ * Because the unit of measure of the value in the SfxItemPool is only
+ * queryable via @see SfxItemPool::GetMetric(sal_uInt16) const (and not
+ * via the SfxPoolItem instance or subclass, the own unit of measure is
+ * passed to 'eCoreMetric'.
+ *
+ * The corresponding unit of measure is passed as 'ePresentationMetric'.
+ *
+ *
+ * @return SfxItemPresentation     SfxItemPresentation::Nameless
+ *                                 A textual representation (if applicable
+ *                                 with a unit of measure) could be created,
+ *                                 but it doesn't contain any semantic meaning
+ *
+ *                                 SfxItemPresentation::Complete

+ *        Because the SvxColorItem does not know which color it represents
+ *        it cannot provide a name, which is communicated by the return value
+ *
+ *    pSvxBorderItem->GetPresentation( SFX_PRESENTATION_COMPLETE, ... )

+ Design Notes
+ -------------------------------
+
+ This class is extremely heavily used - we can have millions of broadcasters and listeners and we can also
+ have a broadcaster that has a million listeners.
+
+ So we do a number of things
+ (*) use a cache-dense listener list (std::vector) because caching effects dominate a lot of operations
+ (*) use a sorted list to speed up find operations
+ (*) only sort the list when we absolutely have to, to speed up sequential add/remove operations
+ (*) defer removing items from the list by (ab)using the last bit of the pointer
+
+ Also we have some complications around destruction because
+ (*) we broadcast a message to indicate that we are destructing
+ (*) which can trigger arbitrality complicated behaviour, including
+ (*) adding a removing things from the in-destruction object!

+We are currently not able to fully support a switch to another calendar during
+input for the following reasons:
+1. We do have a problem if both (locale's default and format's) calendars
+   define the same YMD order and use the same date separator, there is no way
+   to distinguish between them if the input results in valid calendar input for
+   both calendars. How to solve? Would NfEvalDateFormat be sufficient? Should
+   it always be set to NF_EVALDATEFORMAT_FORMAT_INTL and thus the format's
+   calendar be preferred? This could be confusing if a Calc cell was formatted
+   different to the locale's default and has no content yet, then the user has
+   no clue about the format or calendar being set.
+2. In Calc cell edit mode a date is always displayed and edited using the
+   default edit format of the default calendar (normally being Gregorian). If
+   input was ambiguous due to issue #1 we'd need a mechanism to tell that a
+   date was edited and not newly entered. Not feasible. Otherwise we'd need a
+   mechanism to use a specific edit format with a specific calendar according
+   to the format set.
+3. For some calendars like Japanese Gengou we'd need era input, which isn't
+   implemented at all. Though this is a rare and special case, forcing a
+   calendar dependent edit format as suggested in item #2 might require era
+   input, if it shouldn't result in a fallback to Gregorian calendar.
+4. Last and least: the GetMonth() method currently only matches month names of
+   the default calendar. Alternating month names of the actual format's
+   calendar would have to be implemented. No problem.
