Re: [xtm-wg] association : Type, Subject, Id, Reference

["Thomas B. Passin" <tpassin@home.com>]

Sorry that I only have a few minutes right now, so only a hasty thought -

I agree with Bernard here that it is desirable to be able to refer to an
association instance.  It seems natural to me to do that by giving an
association an optional id.   Since the association has (a) type, and could
have an id, I think assertions about associations could be handled OK.

Gotta run ...
