Property Copying

The property copying "feature" of the HTML+RDFa 1.1 specification feels to
me like it is in the wrong place.  It should be part of the core for RDFa.

This feature would be better placed on the top priority list for RDFa 1.2.

I fail to see why we need to complicate HTML processing nor introduce the
complexity of "in HTML but not elsewhere" for this feature right now.

I also worry about the complexity of adding this for in-browser
implementations at this stage of RDFa adoption.

considered."
