Yes, much as I like the idea, I think we should put the feature into microdata rather than wedge it in through this spec.

As _contextual_ was never used in a registry, and usage in the wild favors the vocabulary setting, support for _contextua_l has been eliminated, and consequently support for the propertyURI element within the registry. This issue remains open pending community review; specifically, anyone depending on this feature should provide feedback as requested below. (see issue 10 [7])

Although the previous registry did have such a setting for some schema.org values, this is not honored by most search engines, and so has been dropped, and consequently support for the multipeValues element within the registry. This issue remains open pending community review; specifically, anyone depending on this feature should provide feedback as requested below. (see issue 10 [7])

>>>  • Lastly, the previous update introduced Vocabulary Expansion using entailment rules adopted from [RDFA-CORE] under control of the vocab_expansion option. Support for Vocabulary Expansion has been substantially simplified, and is no longer under control of an option. This issue remains open pending community review; specifically, anyone depending on this feature should provide feedback as requested below. (see issue 10 [7])
