How about avoiding giving BNF which you then prohibit using? Just list them:


URI scheme name
    jabber

Status:
    Permanent

URI scheme syntax:
     One of the following:
       - jabber:client
       - jabber:component:accept
       - jabber:component:connect
       - jabber:iq:auth
       - jabber:iq:gateway
       - jabber:iq:last
       - jabber:iq:oob
       - jabber:iq:privacy
       - jabber:iq:private
       - jabber:iq:register
       - jabber:iq:roster
       - jabber:iq:rpc
       - jabber:iq:search
       - jabber:iq:version
       - jabber:server
       - jabber:x:conference
       - jabber:x:data
       - jabber:x:encrypted
       - jabber:x:oob
       - jabber:x:signed

  URI scheme semantics.
        These URIs were used as   XML namespaces during development of the technology
        that became the Extensible Messaging and Presence Protocol (XMPP).  
       The scheme was never used (and should not be used) for any
        other purpose; no other "jabber:" URIs shall be minted.

   Encoding considerations.
        ASCII (UTF-8) within XMPP protocol streams.

 Applications/protocols that use this URI scheme name.

       Extensible Messaging and Presence Protocol (XMPP).


  Interoperability considerations.
       The 'jabber' scheme must not be used to identify or
       enable interaction with XMPP addresses; the 'xmpp'
       scheme defined in RFC 5122 is to be used in such
       cases.


  Security considerations.
       See Section 13 of RFC 6120.
