Section 25.1 says:

    srvr           =  [ [ userinfo "@" ] hostport ]

It should say:

    srvr           =  [ [ userinfo ] hostport ]

Notes:

The character "@" should not appear in this rule since it already appears at the end of the rule "userinfo":

userinfo = ( user / telephone-subscriber ) [ ":" password ] "@"

According to the use of rule "userinfo" in other rules such as "SIP-URI" and "SIPS-URI", the correct place of character "@" is really at the end of rule "userinfo" and not in all other rules using it.
