AX 2.0 will allow attributes to have metadata, so an OP would be able to 
indicate that an email address was verified. OPs will probably also be 
able to say when the address was verified, and whether or not the OP is 
also the email provider for the address.

Whether or not an RP should trust an OP to make claims about a user's 
email address is a different discussion altogether.
