Resolutions
  1. The two default profile URLs should be http://www.w3.org/profile/rdfa-1.1 and http://www.w3.org/profile/html-rdfa-1.1 link
  2. Re-introduce @version in XHTML+RDFa 1.1. If an RDFa Processor sees the string "RDFa 1.0", then it is processed as 1.0. If it sees "RDFa 1.1", it is processed as 1.1. If the processor does not see @version in XHTML+RDFa, the latest processing rules are used. If a Host Language doesn't allow specification via @version, the latest processing rules are used. link

Any objections if we keep it the same?

16:22:57 <manu1> Nathan: RDFa is seen as an extension of HTML, not a part of HTML - if it's an extension, do we need a version for the extension?

16:33:24 <manu1> PROPOSAL: Re-introduce @version in XHTML+RDFa 1.1. If an RDFa Processor sees the string "RDFa 1.0", then it is processed as 1.0. If it sees "RDFa 1.1", it is processed as 1.1. If the processor does not see @version in XHTML+RDFa, the latest processing rules are used. If a Host Language doesn't allow specification via @version, the latest processing rules are used.
