+    \ingroup messaging
+
+    \preliminary
+    \brief The QMessageFolderId class provides a unique identifier for a QMessageFolder message 
+    folder, within the scope of the messaging store.
+
+    A QMessageFolderId can be constructed from a string, or converted to a string with toString().
+
+    A QMessageFolderId instance can be tested for validity with isValid(), and compared to other 
+    instances for equality.
+    
+    If the message a QMessageFolderId identifies is removed from the messaging store then the 
+    identifier will not be reused.
+    
+    \sa QMessageFolder
