Hi,
In the course of working on XQilla, I've been getting an
IllegalArgumentException when I'm using the XMLGrammarPool with Xerces-C
2.8. Boris brought this to my attention, and it's slightly odd since it
only seems to occur with attribute groups in schemas. I've attached
sample code, XML and XSD that will reproduce the problem.
I realise I'm probably doing things that most people won't ever need to
do with Xerces-C. Never-the-less is what I'm trying to do valid, and if
so is the IllegalArgumentException a bug in Xerces-C?
