My subtleties:
1. An identifier can name various entities within the endpoint. It is
important to qualify the identifier accordingly. In the RRG context,
an identifier names the Sqglz entity within the endpoint.
2. The 'locatorness' and 'identifierness' of an address may vary
between scopes and over time.
As for the exact definition of a Sqglz, I'm not sure we resolved
that yesterday.
