I don't understand.  Do you mean msxml:script?

I hardly think that association helps your case.

xsl:script is a matter of technical argument.  The language binding issue is 
where politics comes in.  There is no doubt that XSLT 1.1 as is creates a 
caste system of languages.

If Java developers decide to standardize such bindings, or ECMAScript or 
Python developers for that matter, why don't they do so in a separately 
layered specification?
