Thanks for trying to help nail the terminology down, David.

Keep in mind that this language pre-dates the most recent discussions
about terminology that we've been having. We should wait to change the
definition until after the most recent terminology vote completes next
Wednesday... but you're right, it doesn't quite hang together anymore.

Close, but not quite accurate. This is more accurate:

A TBD credential is a set of claims made by one entity (the Issuer)
about a Subject (which is often, but not always, a Holder).

You can view some of the more recent terminology attempts here:

We'll have to wait on this one until after the vote closes next
Wednesday. One option is to say:

A set of credentials forms one of possibly many /identity profiles/ of
the entity.
