Comment on usage restrictions on "dotless" domains.

[Mark Andrews <marka@xxxxxxx>]

While the proposed contractual restrictions on the use of MX, A and AAAA 
records are good, they are likely to be worked around in many protocols by the 
use of SRV and similar records in the future. For example if SRV support is 
ever standardised for HTTP then the use of "_http._tcp.example" would introduce 
the same problems that the restriction on the use of MX, A and AAAA  is trying 
to prevent.

Now while one could ban the use of SRV record with a dotless base name, there 
are non ambiguous uses such as finding whois servers for a TLD, so a careful 
balance needs to be struck.
