It sounds like you're proposing that an RP trust the email claim from an OP
if the domain of the OP and the domain of the email match.  Is that right?
 If so, what's to stop me from setting my myrogueOP.com, and asserting an
email claim for myinvalidemail at myrogueOP.com and getting into web sites
without a valid email address?
