[Ietf-not43] transaction settlement issue stated in Appendix B.

[Andrew Newton]

 From Appendix B. of the new draft:

>       Query Distribution and Non-generic Query Referrals - The working
>       group has discussed issues surrounding query referrals and their
>       impact on certain classes of servers in a query referral mesh.
>       Proposals have been suggested for a robust referral mechanism and
>       a separate transaction token-passing system to provide a means to
>       solving this class of problems.

Given the lack of response on this issue and going by the notes from the 
last meeting in this area, here's my attempt to tackle this one:

Query Relay Bag

When issuing a referral, the protocol MUST be capable of supplying a
relay bag from the server to the client, and the protocol MUST be
capable of allowing the client to submit this relay bag with a query
to the referred server.  The use of the relay bag MUST be OPTIONAL.
The protocol MUST NOT make any assumptions regarding the contents of
the relay bag, but the relay bag MUST be described using the
schema language of the protocol.
