Hi Eric,
I'm having trouble with the RNG approach. I've created a test rng and test xml
with xmllint that can create the problem I am seeing, specifically:
test.rng:
<?xml version="1.0"?>
<grammar xmlns="http://relaxng.org/ns/structure/1.0"
datatypeLibrary="http://www.w3.org/2001/XMLSchema-datatypes">
<start>
<ref name="video"/>

<define name="video">
<element name="video">
<optional>
<element name="model">
<attribute name="type">
<choice>
<value>vga</value>
</choice>
</attribute>
<group>
<attribute name="type">
<value>qxl</value>
</attribute>
<optional>
<attribute name="ram">
</attribute>

</group>
The critical part you are missing is that the attribute type=vga and the
group containing attribute type=qxl need to be within a choice element.
That is:
<element name="model">
<choice> <!-- this is important -->
<attribute name="type">
<choice>
<value>vga</value>
...
</choice>
</attribute>
<group>
<attribute name="type">
<value>qxl</value>
</attribute>
<optional>
<attribute name="ram"/>
</optional>
</group>
</choice>
...
<optional>
<attribute name="vram">
</attribute>
</optional>
</element>
</optional>
</element>
</define>
</grammar>
