Adobe have announced a project for representing PDF in XML called Mars. They have also announced a project to cooperate with Mozilla on a shared ECMAScipt project codenamed Apollo. (Javascript is formally known as ECMA Script, Adobe/Macromedia has long had a version called Actionscript but I still like the original name Livescript best.) Not so relevant to inkscape at the moment. It also sounds vaguely like they are going to use Webkit (KHTML) but that has even less relevance to Inkscape.
The interesting part of all this project Mars relevant to Inkscape can be found buried in the Frequently Asked Questions: http://labs.adobe.com/wiki/index.php/Mars:FAQ#What_advantages_does_SVG_bring... "SVG is an abbreviation for Scalable Vector Graphics, an XML-based, W3C standard language for describing graphics. Many applications and tools can create or manipulate SVG page contents. SVG page content can also be converted to PDF graphic operators using Acrobat 8.0 Professional and the Mars plug-in."
I'd love to give you more details but so far I only know as much as can be seen in the FAQ. http://labs.adobe.com/wiki/index.php/Mars:FAQ
Looks promising. You might even say it was pretty cool.

P.S. I know I should probably add this to the Wiki and I probably will eventually but I welcome the help of anyone who wants to do it first or even find better information.
