Sure.  There may be multiple entities that are interested in the class of
events, perhaps applying different filtering.  However, this case wouldn't
require the use of the "id" parameter IMO (at least one of the tags and
Call-ID would be different).

I'll admit I don't have a scenario at the moment that would use this
capability.  But SIP Events supports it.  BTW, the "id" parameter is
optional.
