Indeed.

A real-world problem.  FWIW, I think that in the next-next release of 
both Firefox and Safari, they will have partial support for SVG 
Fonts.... maybe a year, year-and-a-half way, hopefully.

In the meantime...

Silly humans with their big brains.  Please find attached a moderately 
workable solution to the problem of a lack of SVG Font support.  Simply 
add in the Real Text, with a suitable-enough font to match the size and 
style of the logo, positioned more-or-less correctly, and set the 
opacity to zero.  Nothing shows to mar the nice rendering, but it has 
the text content, and it makes the faux-text seemingly selectable 
in-place and findable (and indexable).  This doesn't work well for 
dynamic content, but it's fine for static graphics.

I also added a <title> and a <desc> element with some suggested text.

This is not to diminish the inclusion of RDF, particularly with 
copyright info, etc.... but that's for a different purpose, I feel. 
Text intended to be human-readable (that is, rendered) in SVG should 
always be included using one of the text-content elements (<text>, 
<tspan>, <tref>, <textPath>, and <textArea>).

I'd like to see this done with all W3C logos, and I'm willing to put 
some cycles to it.
