This seems reasonable to me.  Rather than the XML Schema working group
essentially reinventing a less-powerful version of Schematron, wouldn't
it be more beneficial to the marketplace if the XML Schema working
group created standard "hooks" for inclusion of Schematron
patterns/rules/assertions?  Then a user has the option of implementing
data validation requirements either by embedding Schematron into an XML
Schema, or keeping the schemas separate in a pipeline fashion.

And hey XML Schema working group, how about also creating standard
hooks for inclusion of other schema languages, such as Relax NG and
RefleX?  And how about supporting a building block approach to
implementing data validation requirements?

Rick Jelliffe, how about jumping into this discussion?
