Hi.

I wonder if there is any merit to a feature that would allow script to
load a resource document from script.  This would be different from
using the URLRequest interface in that it's a proper SVG document
"running in the background", as described in section 17.1.

I'm trying write an sXBL definition that has an xlink:href type of
attribute.  I want to track the referred element for changes so that my
custom element can change in response.  But I don't want to load that
document in a completely insular way: if the referred element changed,
then any of my custom elements should be updated.  The referred element
could actually be in the same document, but I couldn't be sure if I got
a URL, since I would have to perform the same HTTP redirect checks that
the UA should do for resource documents.

A way around this would be to insert a hidden svg element into my
element's shadow tree and then access the resource document via the
SVGElementInstance tree.  It seems a bit hackish, though.

Is this a far-fetched use case?

Cameron
