Hi Dean, > I request that having a doctype for RDFa in XHTML1.1 documents become a > MUST (compulsory), and not optional. As most people send their XHTML > documents as text/html [1], a doctype will be needed to trigger > standards mode, plus the lack of a doctype creates a conflict with the > XHTML variant of HTML5. Thanks for your feedback regarding RDFa in XHTML1.1. At this point, because we have already considered this exact issue thoroughly, and because there is no new evidence, we do not believe that changing the specification is warranted. I want to stress that, though your comment came after the deadline, we discussed it fully during our call based entirely on the merits [1]. - existing issue, discussion and resolution: http://www.w3.org/2006/07/SWD/track/issues/106 In addition, a related issue and its discussion can be found at http://www.w3.org/2006/07/SWD/track/issues/28 - ways in which we address this issue in the current specification: We explain in the Document Conformance section [2] the required use of the html element with the proper xhtml namespace reference. We also recommend using @version on the html element. We explain in the informative appendix that, if one wishes to validate using the existing validator, then one needs to include the DOCTYPE [3]. There should be no confusion regarding validation, though we note that validation techniques may well evolve (XML schema-based validation is an active area of work at W3C.) - HTML5: HTML5's XML serialization does not require DOCTYPE. This is, in our opinion, evidence that DOCTYPE need not be mandated, as other languages are already choosing to omit it. Thanks again for taking the time to send us a detailed comment. Please let us know if this resolution is acceptable to you. -Ben Chair, RDFa Task Force.
