Yes indeed.

For the particular job, we don't have that problem, but for the XSD to
Schematron converter we are working on I've put out some XSLT
stylesheets to macro-process the includes, imports, complex type
declarations, groups and attributeGroups. This can give a big file, but
many fewer cases to deal with.

Anyone interested, see

Fixes, improvements, welcome.
