Why don't self-closing script elements work?
What is the reason browsers do not correctly recognize:

To add to what Brad and squadette have said, the self-closing XML syntax
actually is correct XML, but for it to work in practice, your web server also needs to send your documents as properly formed XML with an XML mimetype likeapplication/xhtml+xmlin the HTTP Content-Type header (and not astext/html).However, sending an XML mimetype will cause your pages not to be parsed by IE7, which only likes
text/html.From w3:
In summary, 'application/xhtml+xml' SHOULD be used for XHTML Family documents, and the use of 'text/html' SHOULD be limited to HTML-compatible XHTML 1.0 documents. 'application/xml' and 'text/xml' MAY also be used, but whenever appropriate, 'application/xhtml+xml' SHOULD be used rather than those generic XML media types.
I puzzled over this a few months ago, and the only workable (compatible with FF3+ and IE7) solution was to use the old
syntax withtext/html(HTML syntax + HTML mimetype).If your server sends the
text/htmltype in its HTTP headers, even with otherwise properly formed XHTML documents, FF3+ will use its HTML rendering mode which means thatwill not work (this is a change, Firefox was previously less strict).This will happen regardless of any fiddling with
http-equivmeta elements, the XML prolog or doctype inside your document -- Firefox branches once it gets thetext/htmlheader, that determines whether the HTML or XML parser looks inside the document, and the HTML parser does not understand.
