This is main specification of qubes.xml in RelaxNG. It should not <include> any
other file. If you need to extract some part of specification, just put the part
in question in separate <define> and create small boilerplate schema like this:
<?xml version="1.0" encoding="utf-8" ?>
<grammar xmlns="http://relaxng.org/ns/structure/1.0">
<include href="qubes.rng">
<start>
<ref name="domain" />
</start>
</include>
</grammar>
Don't forget to put <start> *inside* the <include>. If you'd put it outside,
the parser will complain about missing combine= attribute on the second <start>.
