Although the spec resulting from CC/PP will likely be interesting, I think its
intended use needs a change.

Yes - I'm no Microsoft basher, but let's face it - even if CC/PP comes out as a
solid spec, Microsoft isn't going to use it.

Perhaps more importantly, no browser vendor is going to use it effectively on their
own. What would be very useful to authors as a result of CC/PP is a central,
authoring community-controlled repository for CC/PPs (hint: W3C). A total profile
that is comprehensive to authors, perhaps controlled by a dedicated W3C list,
could be maintained, and that profile, not unlike a DTD, could be referenced by
URL for feature support.

With that in place the only CC/PP problems remaining would be:

* Browsers that don't bother checking the W3C CC/PPs, and use their own or none.

* Old browsers, and the need for something like a .js include that will check the
CC/PP for you.
