Being able to take a few passes at the data is a really useful technique.
The effective schema is an intersection of schemas.
It is built into Schematron (each pattern equivalent to a pass, though it
may not be implemented that way), and I see James Clark was able
to represent the exclusions in HTML using three passes in RELAX NG
(one for the general schema, one for the restriction that an <a> cannot
contain a child <a> at any level, and something else: presumably
XSD would require the same, sniff :-)
