I think only the dialog identification elements should be mandatory. 
Others are there only to allow some extra functionality. For example if I 
lack a contact, then I can still keep track of the dialog, but I will not 
be able to end it by sending a BYE.

Such dialogs can be marked as impure/incomplete and they will lack certain 
features that the others have. I think that only missing mandatory dialog 
identification elements should be considered an error.
