+/** defines the interface for creating bridges to other object models.
+
+ <p>
+ The created bridges are transparent to the user. That is, if one maps
+ an interface into the target model, then the resulting target interface
+ is a bridge implementation, that is not being noticed by an user. During
+ a call on that interface, the bridge is invoked to convert the arguments
+ and carry out a call according to the rules of the source model.
+ Return values are automatically mapped to the types of the target model.
+ </p>
+ <p>
+ Simple types are mapped to simple target types. That is, there is no additional
+ bridging code involved when those types are being used.
+ </p>
+
+ <p>Sometimes a bridge cannot be created, depending on whether a program uses
+ the XBridgeSupplier2 interface remotely. Assuming one wants to bridge an
+ OLE Automation object to UNO by calling createBridge on a proxy, then the UNO remote
+ bridge would not recognise that the Any argument contains an IDispatch interface.
+ Therefore it cannot marshal it as COM requires it and the bridgeing would fail.
+ To prevent this, implementations of this interface should be aware of this scenario and
+ if necessary take the appropriate steps. The process ID argument to the createBridge
+ function represents the calling process and may be used by the implementation to determine
+ if it is being accessed remotely.
+ </p>
+ <p>All objects, whether they are part of the UNO object model or not,
+ are carried in an `any`. The representation of this object
+ is heavily model-dependent and has to be specified in the following list: </p>
+
+ <dl>
+ <dt>UNO: </dt>
+ <dd>The any carries normal UNO types, which can be any base type,
+ struct, sequence, enum or interface. </dd>
+
+ <dt>OLE: </dt>
+ <dd>The any carries an `unsigned long` (on 32-bit systems)
+ or an `unsigned hyper` (on 64-bit systems), which is
+ interpreted as a variant pointer. The any does not control the
+ lifetime of the represented variant. That implies that the caller
+ has the responsibility of freeing the OLE resources represented
+ by the any value. </dd>
+
+ <dt>JAVA: </dt>
+ <dd>not specified yet. </dd>
+ </dl>
+
+ </p>
+ <p>Any implementation can supply its own bridges to other object
+ models by implementing this interface and returning the bridge
+ when the method XBridgeSupplier2::createBridge()
+ is called with itself as the first parameter. </p>
