The resolution process in RFC 3263 is a monster... It takes as input a URI, whose important parts are the scheme (sip: or sips:), hostpart (host address or DNS name), port (explicit or omitted), and transport parameter value. Its output is a prioritized list of triples, each of which is an IP address, a port number, and a transport (UDP, TCP, or TLS). How WS/WSS fits into the system, I don't know. Perhaps it's been specified in a later RFC.
