We can tweak it to:

   As an example, given an input URI of "sip:alice:pswd@
   example.net;transport=tcp?subject=project%20x&priority=urgent", the
   client derives the service type "sip" from the scheme and the domain
   name "example.net" from the authority component.  Also, given an
   input URI of "im:[email protected]", the derived service type might
   be "sip", depending on how the example.net service is deployed (since
   the "im" scheme [CPIM] is defined as an abstract scheme in the SIP
   context by [SIP-IM]), and the domain name would again be
   "example.net".
