 Gudge,
 the original wording was that the parameters appear in the same 
order as in the function signature and that the return value 
accessor MUST be first. We cought that MUST in the RPC task force 
when we decided that the RPC element is modeled as a struct and 
that the return value accessor has a special name. The SHOULD is 
there to keep continuity.
 Now you caught that there is another, implied, MUST in the words 
"these appear in the same order ...", which I think we would have 
weakened to a SHOULD, too, if we caught it first in the RPCTF.
 We can try and remove the ordering stuff altogether but I think 
that what I suggest in the paragraph above is a satisfactory 
solution which keeps as much of the SOAP/1.1 rules as acceptable.
 What do others think?
