We believe that the requirements for SCDs should include a requirement to
support metadata querying in an XQuery or XSLT environment. This entails two
requirements.

First, it is a requirement that SCDs be able to denote arbitrary schema types
or element declarations. (We believe the current draft supports this
requirement adequately.)

Second, in the long run a full-scale search facility on schema components will
be needed, to enable finding things like "the set of types derived from type T"
or "the set of elements substitutable for element E". Some members of the QT
Working Groups expressed reservations on this topic, and whether search
facilities should be embedded in SCDs or supplied by an environment like
XQuery.
