Thanks. Just what I was looking for.
Yes, "brushed aside" had an unintended incendiary effect. That was not my
intent, but I am guilty as charged.
I can accept "unashamedly political."
Type assignment will likely be a high priority for RELAX NG 2.0. I suspect
it will be presented as a modular spec.
