Hmm, not what I was going for... I was trying to avoid talking about
subject identifiers by just using "Jane" as the subject identifier.

Unfortunately, this isn't accurate. Claims are made about subjects,
where the subject is the holder in the vast majority of cases. The
subject may not be the holder (for example, you holding on to a claim
made by a veterinarian about your pet).

We could reword to:

Claim: A statement made by an Issuer about a Subject. For example,
  "A hospital (Issuer) says that Jane (Subject) is
   a doctor (the claim)."
