This isn't quite true.  DCMI has defined and published an XML schema for
simple DC. See


(I would hope that a similar schema for qualified DC will be released

However, it is worth noting that the simple DC schema is specifically
intended for importing into other, applicationp-specific schemas.
Therefore it does not define a container element for the DC record - it is
up to the application to define that.

An example of how this works is demonstrated by the DC schema used in
version 2 of the OAI-PMH...


It would be nice for SRW to have used the same mechanism


On the other hand, I don't see any obvious incompatabilities between
the resulting instance metadata generated by the two approaches?
