I think most people would be happy to get something together, even if it's 
not Explain mapped directly into XML.

If someone [tm] were to map out an attribute architectured way of 
searching explain like records, then you could return them in GRS1, XML, 
SUTRS or whatever else you wanted.  Just put them into a database 
called... iR-exPlAin-2 [1] or whatever was agreed upon.

Of course this means that vendors would need to implement the attr arch, 
but they were going to do that anyway for Bath compliance, right? :)

You then don't have to worry about either taking an unnecessary hit on 
init, or somehow connecting to a web server to get information about the 
Z server.  Finding out where to go for the webserver is of course yet 
another question that's unanswered -- may as well just use what we've 
already got, eg Z39.50 databases with records in them.

Probably, but you have a big project behind you who all have to use it ;)
If you count all the Cheshire servers, then we may have you beat for 
Explain capable machines.
