That would make sense, but now I am confused.  The text quoted below 
seemed specifically to indicate that it would not be there:

>> The return value outbound edge MUST NOT be 
>> present if the return value of the procedure is void

What am I missing?

 Noah,
 it is impossible to omit some members in an array. Therefore, if 
the first member is meant to be the return value (and we know 
that from the signature), it will always be there, even if null 
(marked with xsi:null="true"). If the text needs some rewording 
to show that, I won't object to it. 8-)

 Anyway, the quoted text will be gone if we accept my full
proposal.  8-)
