Great! This means this is not a bug in SAXON , but SAXON does
this on purpose! I'm very glad.

<xsl:stylesheet  
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
    xmlns:xt="http://www.jclark.com/xt";
 version="1.0">

This was the header of my stylesheet. It says version="1.0".

This means SAXON already allows me to write XSLT 1.1
using version="1.0". Right? 

This means stylesheets I write in SAXON are not portable.
( in the universe of version="1.0" )

To understand how this fits into entire picture of 'conformance' 
and 'standards' is not for children like me. 

I give up.
