Question about annotation IDs

So.... while I don't think the spec says this, I assume that the ID
property of an annotation MUST be an absolute IRI.

If that is not the case... I can change the server tests to impute the
absolute IRI based upon... something.  But I don't know what that something
should be.  Probably if the ID starts with a '/' it is relative to the
scheme + hostname + port we are referencing for the collection, and if it
doesn't start with a '/' it is relative to the container URL.

Anyway, help?
