Hi,

A couple of questions related to some comments on GitHub:

Q1: In an offer or answer, it allowed to include fingerprints that have NOT been used to assert the identity?

Q2: If one or more of the fingerprints used to assert the identity change, I assume that the Identity attribute value will always changes a result? Or, is there a chance that different fingerprints would produce the same Identity attribute value?

Regards,

Christer
