Now I'm really confused.  Are you saying the SRV-ID is optional?  If so, 
what's the point of it?  In nearly all cases, there's no way for a CA to 
tell what SRV-IDs it should allow, so nobody will use them.

(This is in addition to the problems that a large mail host handles tens 
of thousands of domains, and the list changes every day.)
