Well, David fixed the bug (in git HEAD) by making sure that the ref label is a string. But that leads to the next problem... Why are there so many refs when parsing this schema in the first place? When I try to serialize this back out, I get:
<?xml version="1.0" encoding="UTF-8"?>
<grammar>
<start>
<ref name="ANONYMOUS3160"/>
</start>
<define name="ANONYMOUS3160">
<element>
<name ns="urn:ietf:params:xml:ns:vcard-4.0">
vcard</name>
<choice>
<empty/>

...
And all of these anonymous refs seem to only be used (well, many of them anyway). Couldn't they just be replaced with the definition?
