I'd say that that should only be allowed to work if the client
provides the ticket and the URL (of course in the Request URI), and
if those in fact match up, then the server provides information on
that particular ticket. We don't want to open up for abuse of
finding previously unknown tickets obviously.
But this might not be a property any more, or at least it might be a
different property. The closest similarity is to the "current-user-
privilege-set" calculated property defined in ACL (RFC3744), which
returns the privileges of the current user. If we modeled a solution
after that we'd have a 'ticket-info' property which, for the ticket
(s) provided in the Ticket header, returned what they were good for.
I think this is a reasonable addition to the ticket draft.
