Ditto. But to me that suggests what I think David is saying - let's figure
out how the thing has to work before we try to push it into a particular
version... In particular, I am not sure we will get this right if we are
trying to wedge it into HTML5 (which is by and large stuff that was
deployed years ago, and a few things that we are still cleaning up like
video after the benefit of a few years of working with it).

In practice, building a spec, deploying it in browsers and content so we
get implementation experience, and then blending it into the HTML.next as
a fundamental piece seems a better approach than trying to get it all into
HTML5. After all we already assume there will be another version that will
be more or less a set of extensions and improvements to HTML5. (Although
we did assume that with HTML 4, it didn't really work out that way for a
few years - so being watchful is important).

I don't care if stuff is taken up by WHATWGCG, by web apps, by HTMLWG -  
doing the work carefully is important. Different people prefer to work in  
different places, but I think what is important is to engage with the  
people who are developing a technology and try to get it right first time,  
rather than waiting for them to take it to a different forum just because  
it is easier or more comfortable for me to work there. (Much as I would  
*like* to have everything done in the places I am most comfortable... and  
to be right always and to find the answer easily...)
