+	/**	Identifies the location of a file and a particular content object inside it.
+
+	TVirtualPathPtr points to the two descriptors (the URI and UniqueId) used 
+	to initialise it. These descriptors must not be modified or destroyed while 
+	the TVirtualPathPtr object is in use. 
+	
+	The URI must be in the format specified in RFC2396, found at http://www.ietf.org/.
+
+	The UniqueId will be created by the Agent. Content is only ever
+	accessed by one agent so it is the agents responsibility to ensure the 
+	UniqueId is truly unique within the file.
+
+	It is also possible to flatten a virtual path into a single descriptor. The
+	ContentAccess::CVirtualPath class concatenates the URI, a separator, the KCafVirtualPathSeparator
+	character, and the UniqueId to form a single URI. TVirtualPathPtr can be used to 
+	decode this virtual path into the URI and the content object UniqueId. The 
+	concatenated URI and UniqueId take the format:
+	@code
+		<URI><KCafVirtualPathSeparator><UniqueID>
+	@endcode
+	
+	An example of this format is shown below:		
+	@code
+	// Create a CVirtualPath object to point to OBJECT1 inside file.dcf
+	CVirtualPath *path = CVirtualPath::NewL(_L("C:\\directory\file.dcf"), _L("OBJECT1"));
+
+	// convert the URI and unique ID into a single URI.
+	TVirtualPathPtr aPath = path->GetCombinedUriUniqueId();
+	@endcode
+	@note
+	If a URI is supplied which contains multiple KCafVirtualPathSeparator characters 
+	the rightmost KCafVirtualPathSeparator character will be taken as marking the end
+	of the URI and the start of the UniqueId. When multiple KCafVirtualPathSeparator
+	characters are present, under certain situations this will result in an invalid 
+	URI and UniqueId being created for the virtual path and can lead to an undefined failure.
