It's hard enough to write complex queries and get them working correctly with
decent performance.  If a query's guts are obscured by excessive (xml) syntax,
it will be ***much*** harder.  So I am sympathetic to the use of a non-xml
language.

My only concern is that beyond doubt, people will want to include XQL queries
in xml documents.  Perhaps they would be passed along using SOAP, for example
(yes, I know that SOAP could carry non-xml data, but it's not so convenient to
do that).  So how are we going to do that?

Maybe CDATA sections will turn out to be the way.

Cheers,
