OpenDocument is a proposed standard office-type document format; see http://www.groklaw.net/article.php?story=20050130002908154 for its proposed use etc.
Currently it has its own custom format for graphics elements, similar to OpenOffice.org's Draw format, and also somewhat similar to SVG in some areas.
Clearly it would be good both for SVG, Inkscape, and the success of the OpenDocument standard, if OpenDocument were to use SVG to the extent possible, such that any SVG-compliant renderer could render the <svg> parts of the document.
The current OpenDocument specification is available at http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=office .
At the end of its first page, you can see how to submit comments. (See also the inkscape-devel mailing list, subject "filter for inkscape and OpenDocument".)
From Daniel Carrera:
You can leave a comment (click on "Send a comment"), join the TC, or simply just join their mailing list and participate in the discussion. The list is firstname.lastname@example.org but I can't figure out how to subscribe. I know you don't have to be a TC member to participate, as I know of other people who aren't members and still contribute there.
It is very important to get representation in the OASIS TC from multiple interested parties. The goal is to make a format acceptable to everyone, and that can only be done if people participate in the discussion.
Also, right now they wer working on the next version of the format. The one that'll meet all of the EU's requirements. And they are in the official "request for public comentary" period until Friday. So, the best time to raise a concern is right now. Send them a comment.
