You mean RFC2782, which states that 'A Target of "." means that the 
service is decidedly not available at the domain.' - later, in the 
description of how to use SRV records, it merely says 'abort'.

This means your interpretation must be correct - sort of. The server 
could lookup records in _simple.example.com, for instance, if it were 
capable of gatewaying to SIMPLE, but no server to server XMPP service 
is available.

Definitely it's wrong to resolve example.com and try randomly 
connecting to it - not only wrong, but arguably illegal, since you've 
been explicitly told there is no such service at the domain.
