Donald,

I have permission to go ahead and publish a CR but I'd like to fix this 
editorial bit first. ds:DigestMethod can't appear in the schema because it 
causes an ambigous content model problem. Also, the only place we are using 
it and OEAPparams is in the RSA method. So I'd like to make it a sequence 
of an optional KeySize and any, and define those other elements in that 
section. Also, I'd like to promote the EncryptionMethod up to its own 
section -- presently it's hidden at the bottom of the algorithm section.

Does this sound ok?
