think of critical applications based on a large number of XSLT 1.0
stylesheets - how to migrate safely to a consistent use of XSLT 2.0? The list
of subtle incompatibilities ( http://www.w3.org/TR/xslt20 , Appendix J.1 ) is
rather long, and I wonder if there are tools available for automated checking,
assessment of risks and code modifications reducing those risks. (For example,
replacing in certain places the current XPath expression by "(expression)[1]"
is something that comes to mind.) And are there perhaps some recommendations
or best practices how to accomplish the upgrade?
Thank you for any thoughts,
comments or information.
