I won't link to the schema yet. Too many outstanding issues and
inconsistencies. I'll be away next week and when I get back, hopefully you all
will have it all resolved!
Among the issues: I would strongly oppose adding a database name. The database
name in ZNG is analogous to the host in Z39.50 and we don't specify the host in
the request. This was a huge simplification that I hope we don't back out of.
Regarding number of records in response -- I presume that was a clerical error.
The rest of these you all can argue over. --Ray
