	// Each Inkboard message has a context of validity according to an Inkboard 
	// client's state.  That is, certain messages should be acknowledged and processed
	// in some states, whereas other messages should not.
	// For instance, a whiteboard invitation should be acknowledged if an Inkboard
	// client is not in a whiteboard session, but should be refused if said client
	// _is_ in a whiteboard session.

	// Only the flags that are required to be set must be set; all flags, by default,
	// are zero.  Explicit definition doesn't hurt, though.
