Indeed if I wrap XQuery expressions in CDATA sections, then I can store them
as plain text.  I'm hoping for something a bit more useful.  For example, I
would like to be able to build XML-based logic that can dissect and assemble
XQuery expressions using normal XML tools/logic--the kind of things we can
now do with XML Schemas that are not all that easy with DTDs.

I understand that this is not 'the' problem that XQuery is trying to solve.
My hope is that it will not become the problem that XQuery creates.

How about:

<xquery> your xquery query goes here </xquery>

DTD being not a valid XML is not the problem that XML Schema is trying to
