+    \class QMessageContentContainerId
+    \ingroup messaging
+
+    \brief The QMessageContentContainerId class provides a unique identifier for 
+    QMessageContentContainer internet media (MIME) type entities, within the scope of the
+    containing message.
+
+    A QMessageContentContainerId can be constructed from a string, or converted to a string 
+    with toString().
+
+    The identifier of the containing (parent) message is return by messageId()
+
+    A QMessageContentContainerId instance can be tested for validity with isValid(), and compared 
+    to other instances for equality.
+    
+    If the object a QMessageContentContainerId identifies is removed then the identifier may 
+    be reused.
+    
+    If the QMessageContentContainerId refers to an object that has a parent container, and the 
+    contents of that parent container are modified by removing or prepending contents (i.e. 
+    message attachments are removed or a message body is created) or the parent container 
+    itself is removed then the identifier may become invalid, or be reused to reference a 
+    different object entirely.
