Hmmm.  So, I missed that you were targeting the narrower issue of SRV, 
per se, rather than the broader (and shallower) task of attrleaf.

With respect to domain naming -- as opposed to SRV RR details -- the SRV 
spec is more of a template meta-spec -- guidance for later, specific 
specs -- than a detailed spec itself.

As such, one can easily mandate defining a modified template for new SRV 
definitions, going forward.

As John suggests, I think this is independent of the attrleaf task and 
doesn't affect it.
