Structure spec as a vocabulary?

[michael-n-cooper]

Personalization semantics defines a set of attributes, but arguably these attributes mainly serve to define a vocabulary. Other technologies such as RDFa and HTML Microdata could also add similar semantics to content, but that won't be useful unless the vocabulary is standardized. We might want to consider focusing the spec on the vocabulary, and leaving the specific attributes to implementation. Or separate the "vocabulary" aspects of the spec from the "ARIA features" aspects, so the vocabulary part can be reused by others.
