I'm not really sure, and this is broken in any case as the comment points out. We need another element and definition regardless: This isn't valid schema. We need a schema construct that has the content (or a child with the content) of CryptoBinary, *or* a set of transforms. -- Reagle/Dillaway." >3.4 Extensions to enc:KeyInfo Element > > >1.
