Asir,
	See attached artical.  I regard XMLschema, XDR, DTD and SOX as
'fixed' schemas, i.e. the XML must look a certain way to be correct.

	I se Schematron and any rules based 'schema' as dynamic, as I can
satisfy the rules with mor ethan one XML file.

Really !! :-(  :-(

I periodically check XML hack and never came across this one. May I
request you to provide me with a pointer to it?
