There is currently no known rigorous validator. If you find or create one, please submit it to the BBCode 2.0 Working Group Meeting thread so that we all may benefit.
I use the enterprise namespace-aware Apache Xerces-based validator, with proprietary enhancements to support BBCode in addition to XML. Unfortunately I cannot distribute the source.

Send me a CD image and I'll see if I can crack it.
