You should be able to take the "W3C HTML5 spec" and do whatever you want
with it as long as you don't call your derivative work the "W3C HTML5
spec". In other words, besides the trademark, you can do what you want.
Now, understand that I'm not writing on behalf of W3C here. There is no
agreement within the W3C to do such a thing and there are certainly
individuals and/or organizations who are/will be against such a move.
It's a significant shift from the way we've been doing standards so far
and it removes legal protection against improper use of the
specification (besides the trademark). For the moment, the only move
that W3C has been looking into is to make its specifications more reuse
as part of software documents (it's still in progress). So, if we want
to be able to steer W3C further away from its current document license,
I need to go in front of the W3C management and the W3C Advisory
Committee and starts the discussion. Having the backup of a W3C Working
Group and a clear idea of what we want to achieve will significantly
increase the chances of success here (and also increase my life
expectancy in some forum).

I believe that this issue has been resolved. It was an oversight from
some Working Groups who did not realize that having the interfaces
inside the specification had the effect of adding those under the
document license. I have an action item to write something about that fr
the Hypertext CG.
