Using xml:base in an xsl:stylesheet declaration - how about it?

[Dan Morrison <dman@xxxxxxxx>]

I have a problem, & I have a solution.
I just want to bat it around here before I apply it across the board.

Currently there is no documented equivalent to the <BASE href=""> tag in
html for XSL stylesheets.

However, the use of xsl:include & xsl:import rely explicitly on there
being a 'Base URI' available to work from.

Now in my case I'm either parsing & caching my xsl long before the
transform, or in some cases generating it from scratch. I still want to
use xsl:include, but my xsl tree has no Base URI. 

So I want to explicitly define it, and I'd like to do that in a way that
falls within the rules.

I see that this issue as it applies to XML in general has already been
considered in the proposal
http://www.w3.org/TR/xmlbase

Great.

So can anyone give me some good reasons (I mean REALLY good reasons) why
I should not start using syntax like

<xsl:stylesheet 
	xmlns:xsl="http://www.w3.org/XSL/Transform/1.0";
	xml:base="http://my.host/xsl/mystylesheet.xsl"; 
	>

for the purposes of my own development? (or should that be xsl:base?)

And if this strikes a chord, will we be likely to see adoption of this
method in the future?

Awaiting a response (as I'm sure there's something I haven't thought of
that will annoy the spec Nazis out there)

Regards .dan.
