   Hum, the XSLT transform context has its own error handler
       xmlGenericErrorFunc  error;         /* a specific error handler */
       void              * errctx;         /* context for the error handler */
at least the placeholder is tehre, maybe the code doesn't call it.
Can you check ?

   Right, I would have to expose the XSLT parsing context
at the API level which is not done ATM and provide handlers
too in that structure.

  Actually I did that, not released but will be available.
I'm not against adding the APIs necessary for a fully threaded
use, if you're ready to play the guinea pig, why not iron this
out ...
