Chris,  to do that you need to define cmd in two different ways in the same 
scope.  That isn't valid XML Schema to my knowledge.  But you could always 
branch your logic at the level of creating, for example, cmdClient OR a 
cmdServer element when you write the manifest file, and define each 
accordingly, and your processor downstream has to look for both cmdClient AND 
cmdServer as opposed to just cmd.
