Right now one needs to write a customization layer to override templates etc.
Unfortunately this is making the processing even slower. It would be nice to
preprocess the xsl to a single file, resolve constant expressions and kick out
dead codepath. This all in the hope that processing the own xml docuemnts with
the prerpocessed xsl would be faster.
