document-uri() problem in XSLT1 schema when generated by XSLT2 engine

[GoogleCodeExporter]

Lars Hutter has reported the old problem of stylesheet versions caused some 
problem. See discussion at 
http://www.eccnet.com/pipermail/schematron/2010-July/000295.html   

There are two problems:

1) Should @queryBinding="xslt2" cause a stylesheet with @version="2.0". 

According the draft ISO standard binding for XSLT2, backward compatibility 
should be false. See Annex L, http://www.itscj.ipsj.or.jp/sc34/open/1419.pdf So 
that suggests that certainly 2.0 should be generated. (Need to check it is.)

2) The svrl for saxon script generates  document-uri() function even for 
@queryLanguage="XSLT1" schemas. This is good for people then running the XSLT1 
script on SAXON: it allows better reporting, but will fail on XSLT1 systems.  
Sometimes people cross-compile, for example when the compiled stylesheet will 
run on IE attached to an XHTML document. 

At the moment there is some source code comment to delete document-uri(), but 
this requires hacking which we need to get beyond, even if it is an edge-case. 

Need to figure out better system: a command-line switch is one more thing to 
think about?, some use of xsl:fallback maybe?, or what?
