If you use the TEI templates in oXygen, and have updated to the latest TEI version, you'll find that
by default it associates TEI docs with a RELAX NG schema and an ISO Schematron scheme;
the validation uses both at once. Which is a Good Thing.
If you use the TEI "All" schema, you can find yourself running of Java stack size.
it sounds awful (though actually its easily fixed).
However, if you upgrade to oxygen 14.1, you'll find it all just works as expected.
See? you thought this was going to be bad news. It's not, its good news. Upgrade,
and things will be better than ever,
