[xsl] XSLT+XPATH as SVG scripting?

[DPawson at rnib dot org dot uk]

I've spent some time on an SVG list,
and roughly 60% of the posts involve scripting, most
often with javascript.

Functionally the prime usages seem to be animation,
addition and removal (or hiding) of some element
of the SVG document.

Question for the grammar aware readers.

Is it reasonable to suggest that SVG 'build in'
(or whatever)to the rec something akin to what XSLT and XPATH
offer, for this functionality?

There appeared to be very little (functionally) that is
being done that couldn't be addressed using the techniques
found in XSLT.

Find a node, modify its attributes. Its something that
XPATH and XSLT does very easily.

The animations seem to fall into a recursive call
to some named template format, incrementing some
attribute and writing back to the 'document'.

Even the event handling appears to me not impossible:
<svg:eventHandler event='onclick' target='someXpath'>
   modify the memory model of the document
</svg:eventHandler>


Can anyone see anything way off base here?
 In terms of operation, I'm less sure.

Perhaps the SVG browser loads the file,
'compiles' the svg 'script' and acts on it
as required.
