A namespace would work fine for grounding, but due to usability concerns, recent RDFa designs don't namespace-qualify the RDFa attributes. RDFa is a collection of attributes for use with host languages such as XHTML. I recently updated the XHTML 1.x namespace document (http://www.w3.org/1999/xhtml ) to note that the RDFa specs might be one of the places that you have to look to find the meaning of a document that bears this namespace name. -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
