OK, a misunderstanding on my part on how WSDL works.

However I still think its worth defining the format(s) in which
faults will be returned otherwise a client won't be able to
reliably extract an error message: will it be the complete response 
body, within some arbitrary XML structure, embedded somewhere in an 
(X)HTML document?

While the types in the spec may be used abstractly in the WSDL, I
don't think there reason not to mandate them as the preferred format
for the error message.
