Trying to understand SRV records

[Marc.Thach at radianz.com]

Hi everyone especially Kevin and Cricket,
I need to get up to speed with SRVs pretty quickly.

The first problem I have is that Cricket shows an example (p517 4th ed):
     _http._tcp.www.movie.edu.     IN SRV  ..........
Now RFC 2782 says this about the service name:
     If Assigned Numbers names the service indicated, that name is the only
name which is legal for SRV lookups.
But RFC1700 says:
     www-http         80/tcp    World Wide Web HTTP
     www-http         80/udp    World Wide Web HTTP
Has Cricket got his example wrong?

Also does this rule from RFC2782 include registered as well as well-known
ports?  Several of the well-known ports (sql*net 66/tcp; z39.50 210/tcp;
914c/g 211/tcp) have service names including dots, asterisks and slashes.
There is at least one of the registered ports (intuitive edge 1355/tcp)
with a name including a space (a bit like my name really :-) Do you see any
problems with these sorts of names should they start to use SRV?

TIA
