>From time to time over the past several years I have served my Home page as XHTML 1.0 with Content-Type text/html to IE Browsers and with Content-Type application/xhtml+xml to Browsers that recognize that content type -- via Content Negotiation. My current Home Page -- http://jp29.org/ -- is served in this manner. I compose the great majority of my pages using HTML 4.01 Markup (a few using ISO-HTML) and they are naturally served as text/html. I actually started using Content Negotiation for XHTML documents as an experiment to see how the concept worked in practice -- I continue to do so mainly just for fun -- I am growing old and need some diversions from serious work! I also employ Content Negotiation for my XHTML+RDFa test page -- http://jp29.org/rdfaprimerx.php -- there is no "Appendix C" provision (ala XHTML 1.0) in the "RDFa in XHTML (Syntax and Processing - A collection of attributes and processing rules for extending XHTML to support RDF) Working Draft" -- http://www.w3.org/TR/2008/WD-rdfa-syntax-20080221/ -- if XHTML+RDFa documents are served as text/html the W3C Validator adds the following generic note to the successful validation report (quote): "Warning Conflict between Mime Type and Document Type The document is being served with the text/html Mime Type which is not a registered media type for the XHTML + RDFa Document Type. The recommended media type for this document is: application/xhtml+xml" I note that the W3C is currently serving some of their XHTML+RDFa documents as Content-Type text/html. James
