Kevin,

I'm replying to your original message on this, primarily to
demonstrate that I do keep track of issues, even if I am unresponsive
at times!

As Harald has pointed out, the key ASN.1 is missing from the spec.
Interestingly, I did type the data, but simply forgot to include the
file in the parent document.   Here is the missing text:

bilateralTable ATTRIBUTE
        WITH ATTRIBUTE-SYNTAX distinguishedNameSyntax
        SINGLE VALUE
        ::= at-bilateral-table


I think that the case for multiple tables has been argued
convincingly.   However, I note that the GO-MHS WEP type of
collaboration would be much better handled by use of a private routing
community, rather than just a shared MTA table.   The reason for this
is that the community would effectively correlate routing as well as
MTA information.   I will make some appropriate notes.

It has been suggested that the syntax be changed to SEQUENCE.   This
would be needed if an order is necessary on the tables.   I think that
unordered tables will suffice, and that the simpler change of making
the bilateralTable multi-value is better.   I propose to do it this
way.    Any comments?


Steve
