[Sip] draft-ietf-sip-info-events-00: CANCEL???

[Paul Kyzivat <pkyzivat at cisco.com>]

I have a question regarding the following paragraph:

   A UAC MAY CANCEL an INFO request.  A UAS receiving a CANCEL for an
   INFO request SHOULD respond to the INFO with a "487 Request
   Cancelled" response unless the UAC has already sent a final response.
   The UAS then MUST ignore future INFO requests.

Why would the CANCEL affect *future* info requests???
