True.

When you say "server" do you mean implementation or deployment? IIRC, 
SRV support is required for server implementations in RFC 3920, but in 
general specs don't talk about requirements for deployment since that's 
out of scope (we can test software for compliance with a spec, but not a 
deployment -- though in the age of software as a service, that may be 
outdated thinking).
