Implementation of application/x-www-form+xml

[plonepaul]

I'm interested in:

http://www.whatwg.org/specs/web-forms/current-work/#x-www-form-xml

I grepped the source to see if there were any comments anywhere in
Subversion but didn't find any mention of it. I also looked in the
issue tracker and Wiki. Is this on the radar?

I have been thinking about that functionality, but I've been having a hard time coming up with a solution that is technically viable. It is straightforward to encode data as application/x-www-form+xml and post it via XMLHttpRequest, but I am unsure of how to do so by means of form submission. Using XMLHttpRequest isn't a viable solution because it cannot redirect the browser to the URL requested (as far as I know).

Anyone have a suggestion?
