Add doctype=SVG+1.1 to the URL forces validator.w3.org to act as if 
there's a SVG1.1 doctype in the checked document.
Only a selection of all doctypes that validator can handle are in the 
dropdown on that page. I'm promised that SVG1.1 is added to the dropdown 
on an update of that page.

If one of them is not, pick the other

It's not a perfect validator we're going for, but one that is better, 
and hopefully keeps improving (and fix OpenClipArt content with it). 
With the new framework W3C is building, you can have multiple validators 
working together. I have a couple of links on validator development 
activities within the "test" category on http://svg.startpagina.nl

I believe one of the links in that "test" category goes to an e-mail of 
Chris Lilley (THE mister SVG) stating that what i'm doing is conformant 
(for SVG1.1 at least)

Cool, It seems openclipart.org has enough to work from then.

Couldn't agree more
