Known bug: see
https://sourceforge.net/tracker/?func=detail&aid=2878207&group_id=29872&atid
=397617

Please note, if something stops working with a new release of a product,
then it's very likely to be a bug, and as such it should be reported first
on the forum for that product, not here on xsl-list. Both the Saxon and
oXygen lists are very responsive to problem reports.
