Oh!  I assumed we'd want to be consistent with our treatment of 
unrecognized required extensions, but I guess we should ask the rest of the WG.

In the case of required extensions, we do NOT currently require a 
conformant WSDL processor to fault if it encounters an unrecognized 
required extension that appears in a part of the document that the 
processor doesn't need (for example, in a different binding).

If a *part* of a WSDL document is not conformant with the spec, but the 
WSDL processor doesn't need or care about that part (for example, it may be 
in a different binding that the one being used), should a conformant 
processor be required to fault?

What do others think?
