The draft should address the situation where one or more implemented
modules containing deviations are not listed in the "deviation" leaf-list
of the deviated module.

Currently the contents of the deviation list from sec. 3 is ambiguous in
this situation because

1. such a situation might be considered as an error in server
implementation, but it doesn't follow from the document.

2. deviations from implemented modules are applied no matter what the
"deviation" leaf-lists say.

3, the "deviation" leaf-lists are authoritative, i.e. deviations
appearing in other modules are ignored.

I would personally prefer #3 because it is easiest to handle for both
server implementors and clients.
