I suppose it really depends on what you mean when you say "identity".

In YADIS, a URL serves as the identifier for an entity which is usually
a person. A web site also has an identity which happens to be a URL.

How do I indicate to an application what entity I want to operate on? I
give its identity URL. It doesn't matter whether that entity is a
person, a website or a wooly mammoth. The application can then figure
out what kind of thing it's dealing with in terms of what operations it

I've got no problem with the marketing one-liner featuring the word
"identity", since that's the big application right now and it's easy to
clarify if an interested party has further questions.
