RDF in the RDFa Core 1.1 Specification

As RDFa Core 1.1 is now a recommendation [1], it is legitimate to use it the the publication of the rec itself.
If you parse the spec document through an RDFa 1.1 processor, this is what you get:

      The current Web is primarily made up of an enormous number of documents
        that have been created using HTML. These documents contain significant
        amounts of structured data, which is largely unavailable to tools and
        applications. When publishers can express this data more completely, and
        when tools can read it, a new world of user functionality becomes
        available, letting users transfer structured data between applications
        and web sites, and allowing browsing applications to improve the user
        experience: an event on a web page can be directly imported into a
        user's desktop calendar; a license on a document can be detected so that
        users can be informed of their rights automatically; a photo's creator,
        camera setting information, resolution, location and topic can be
        published as easily as the original photo itself, enabling structured
        search and sharing.
      RDFa Core is a specification for attributes to express structured data
        in any markup language. The embedded data already available in the
        markup language (e.g., HTML) can often be reused by the RDFa markup, so
