Hi Mike:

I can see the merit in that (throw away all the SRU schemas), but the thing
that bothers me is new schema being registered (which I am currently anyway
in process of doing for PAM :).

The problem is that we are dealing with different applications and different
communities with their own perspectives and agendas.

I wouldn't necessarily want to have to submit an XML schema intended for an
SRU search app to the OpenURL approval process without that process becoming
more agnostic as to its application. I'm not familiar with how that process
operates but feel that it might not be as straightforward as all that. The
process is anyway outlined here [1] and includes periods of trial use.

For now, though, I am going to continue to register the schema we need with
the current SRU registry.

Cheers,

Tony
