It was always my understanding that the result set id should be supplied by
the server and that it was optional.  If no result set id, then the client
has to resubmit the search.  I don't think that that is complicated.  We
should always ask - could we convince Google and Amazon to implement the
server if we expected xxx?  I'm sure they would rather supply their name
than be expected to echo one supplied by the client.  However, I'm prepared
to live with the server always supplying a name.  But it's the server that
supplies it.  The client can rename it for the user interface.

Ralph --
(1) what does "immutable" mean?
(2) do you still feel that the result set id should be assigned by the
server?
(3) is the ttl just a "hint" or is it stronger than that?  I infered from
one of
Matthew's messages that he thinks that a server is morally bound to keep the
result set available for at least approximately the ttl period (and of
course
morally bound doesn't mean legally bound).
