My parser[1] doesn't follow the WA10 parsing algorithm, either,  
*yet*. However, as a tentative Pythonless Java solution, you could  
use it together with a RELAX NG validator in the pipeline (using the  
whattf.org schemas[2]) to implement Draconian failure in cases where  
the error recovery would kick in as per the WA10 parsing algorithm.

Basically, the parser would report to a ContentHandler splitter. The  
splitter would show each SAX event to Jing/oNVDL first. The validator  
would use DraconianErrorHandler (Jing/oNVDL is fail-fast). Second,  
each SAX event would be shown to a TrAX TransformerHandler.
