Re: request for guidance: centralized extensibility for HTML5 using X3D graphics

Though personally, I would prefer to see X3D integration done as a
separate spec, similar to RDFa+HTML and Microdata. There are a couple
of reasons for this:

* HTML5 is reasonably stable currently. Most changes that happen are
editorial. I'm concerned that integrating X3D would set back the
release schedule for the HTML5 spec.
* As a HTML implementor, I would like to see X3D mature a bit more in
the web world before committing to implementing this. 3D on the web is
still very new technology, especially in the form of markup. It's very
hard for me to judge how likely it is that X3D is the solution that
we'll want to go with.

This doesn't need to make any technical difference. The normative
requirements can be exactly the same with X3D as a separate spec, as
for X3D being part of HTML5. The difference is just an editorial one.

I'm sure there are others that disagree, but I wanted to get my
opinion on the record.

I am however happy to let the HTML WG take on such a work item.
