Switch touch events level 2 to software and document license?

We just switched
<https://github.com/w3c/pointerevents/commit/79e60122e7185bec4485dc7845ea2b49f018548b>
the Pointer Events spec to the new (more permissive) W3C S&D license
<https://www.w3.org/Consortium/Legal/2015/copyright-software-and-document>.
I'd like to do the same for Touch Events, but the process isn't clear to me
since we don't have a WG chartered for TE at the moment.

Doug, is there any reason we can't just update the license in GitHub now?
Obviously we'll still need to go through a chartering or other process when
we get to the point of wanting to publish an official document.

Thanks,
   Rick
