The proposal is up, and, as Creative Commons rep, I cannot live with it 
(it's not even close, frankly.)

First, this gratuitously ignores much existing spec work and much 
existing deployment (Yahoo, CC, MySpace, Slideshare, the UK government, 
the US government, etc.) with a number of use cases that are simply not 
taken into account (Manu has discussed these at length on the WHATWG 
list). When another spec solves the problem and has been deployed by 
significant players, the first step is to consider how that spec can be 
integrated to the fullest extent.

So, I cannot live with something that throws away existing important 
implementations of the *exact* same use cases for no valid technical 
reason. The cost to existing implementors is far too high.

In addition, this proposal *specifically* conflicts with RDFa by reusing 
RDFa attributes (i.e. @property) with a different interpretation. In 
other words, of all possible approaches to the problem, the HTML5 group 
chose an approach that specifically conflicts with the only other 
existing W3C spec for the given use cases. I think this may be a W3C first.

I absolutely cannot live with that.

I note, as a side point, that it's fairly clear this conflict was by 
design (since it was said that @property is "borrowed from RDFa"). In 
other words, whereas typical W3C groups go out of their way to prevent 
conflict with other specs, this group is currently actively creating 
conflict.
