To formally define some sort of a conformance criteria for processors? With all my love to your blog page:-), it would be good to have that documented somewhere, probably on the W3C site...

In my opinion, RDFa 1.1 Lite should be considered an "authoring profile", to make it easier for publishers to markup their web pages using a subset of RDFa. I think suggesting that processor implementors might only implement a subset of RDFa 1.1 would be much more dangerous.

Again, IMO, it should. One of the best things that we did in RDFa was to provide a context where common prefixes are defined. To remove them from a "lite" version would be a big step backwards.
