Agreed, good change, except one place this change introduces ambiguity 
is that now you have two entities; the final two uses of 'entity' 
don't specify which one. The reader will likely interpolate the 
correct one, but there's risk somebody won't.

This is easily fixed; I believe the abstract should read [my change in 
brackets]:

A TBD credential is a set of claims made by one entity (the issuer)
about another entity (the holder). A TBD credential may refer to a
qualification, achievement, quality, or other information about the
[holder] entity. A set of credentials forms one of possibly many 
identities of
the [holder] entity.
