As an aside, I'm likely to oppose this sort of specification as it is 
counter to the rest of the spec where if some bit of variable syntax is not 
present, the semantic is unkown (application defined) instead of an 
implicit (default) semantic.

Otherwise, it looks like we have a couple of options:

1. (the present scheme): the hash is user specified; mgf is SHA-1.
2. the hash and mgf is user specified and they are always the same.
3. the hash and mgf are independently user specified.
