RE: [xsl] Using xsl:namespace-alias for XSL generation in Saxon 6.5.3

["Michael Kay" <mhk@xxxxxxxxx>]

The obvious way to get Saxon 6.5.3 to use the "xsl" prefix in the output is
to switch your usage in the stylesheet: use "x:stylesheet" for the XSLT
instructions and "xsl:stylesheet" for the literal result elements, with
stylesheet-prefix="xsl" result-prefix="x".

I did eventually change this because although it conformed to the XSLT 1.0
rules, it wasn't what people expected or wanted. The XSLT 2.0 rules are much
more precise.
