note 50234 deleted from ref.xsl by bjori

Note Submitter: abel at aberen dot com ---- When migrating from sablotron to this library it's worth the use of the wrapper shared by jw at jwscripts dot com above. Anyway I found more cumbersome to adjust the xsl code since sablotron is more tolerant and less strict than libxslt so chances are that libxslt complains of your code. In such case try to find the offending code and stick to the standard.
