Definition of authority-form in Messaging must require host:port

[royfielding]

In 3.2.3. authority-form it says

The authority-form of request-target is only used for CONNECT requests (Section 9.3.6 of [Semantics]).

authority-form = authority

Whereas it needs to specifically require host:port, as in the definition of CONNECT:

CONNECT uses a special form of request target, unique to this method, consisting of only the host and port number of the tunnel destination, separated by a colon. There is no default port; a client MUST send the port number even if the CONNECT request is based on a URI reference that contains an authority component with an elided port (Section 4.1).
