One of the things I want to do with SRW 1.1 is to restructure the XML
Schema document slightly (making the elements global) so that it is
easier to import and extend the schema. This is merely an editorial
change - the XML structures on the wire don't change just the way that
those structures are described.

This change is primarily so that in principle a schema for SRW 1.1 could
reference the schema for SRW 1.0 (i.e illustrate that it is anm
extension etc.) - similarly 1.2 could reference 1.1, etc.

However, this (and potentiall WSDL 1.2 porttype inheritence) would allow
someone like Theo to create their own bespoke extensions to SRW, i.e.
they can create their own search/retrieve WebService using SRW as a
basis/foundation. A TheoSRW server for instance would support the
searchRetreive operation of SRW as is (hence we have interoperability)
but also a new theoSearchRetreive operation which uses the SRW
searchRetreiveResponse and Request structures with additional bespoke
extensions which Theo's private clients and servers can support.

However, I agree with Mike that the base SRW protocol should not have a
"server becomes creative" flag.
