Not that I know of.  There's no such functionality in SVG 1.1 or SVG 
Tiny 1.2 (for which we are maintaining test suites).

A working example that does what, exactly?

I doubt it.  That was functionality that was included in SVG Full 1.2, 
but it didn't make the cut for SVG Tiny 1.2.  We are currently splitting 
out some bits of SVG Full 1.2 as modules, and may integrate more of it 
into SVG 2.0, but we have no plans to bring the entire existing draft of 
SVG Full 1.2 to Recommendation.  (There would need to be quite a lot of 
rewriting even if we did... that section you point to is actually pretty 
unclear.  The features that are needed in SVG now are not necessarily 
the same set as were included in SVG Full 1.2, and in any case, would 
constitute more than a point-release... therefore, we are moving forward 
with modules and with SVG 2.0.)

None that I know of, but I did manage a neat trick a while back with 
applying an external CSS stylesheet via the XHTML <link> element:

You could try to apply the same technique with RSS and RDF, something 
like...

<xhtml:link rel="alternate" type="application/rss+xml" title="RSS" 
href="url/to/rss/file">

(Don't forget the namespace declaration in the root! You might start 
with my example and change it as needed:

You might capitalize on mixing SVG and HTML for these use cases.  That's 
of particular interest, lately, and we're getting some browser 
development.  This might yield results faster, with more examples to 
draw from.
