Re: Using Saxon 9 as a Schematron 1.5 back end

Hi Henri,

An XSLT 2.0 processor is also a perfectly good XSLT 1.0 processor for 
the large majority of use cases. The incompatibilities between XSLT 2.0 
in backwards compatible mode and XSLT 1.0 are detailed here:

http://www.w3.org/TR/xslt20/#incompatibilities

BTW the reason Saxon doesn't have column numbers in error messages is 
because you can only get very limited location information back from a 
standard SAX parser. I presume Xalan has it's own customized XML parser 
in order to do what it does.
