An old one, as well !</p> <p>Harmful or not, I'd guess some 99% or more "webmasters" have no idea that their lovely XHTML code is interpreted as HTML by every browser on earth, with no benefit from all the XML goodness promised by XHTML evangelists.</p> <p>It has to do with MIME types. While the file name ends in .htm, .html, ,php, or similar, nearly every host will send the document as MIME type text/html. The .php does not work from a hard drive, but the usual setup for files on the hard drive treats .htm and .html as MIME type text/html as well. Not a trace of "eXtensible" markup anywhere.</p> <p>Generally speaking, but not universally true, if you add the &lt;?xml declaration to the beginning of your validating XHTML document, then rename it with a .xhtml extension, it is likely that it will be treated as genuine XHTML. Not guaranteed, but worth a try.</p> <p>Any road up, (mis)using XHTML markup as faux HTML has not broken the web yet. I think that Hickson rather overstates his case.</p> <p>Anyone out there with another experience / point of view?</p> Sat, 01 Dec 2007 02:49:28 +0000 webwiz comment 1226901 at https://www.webmaster-forums.net
