 An XML declaration is not required in all XML documents; however XHTML
 document authors are strongly encouraged to use XML declarations in all
 their documents. Such a declaration is required when the character
 encoding of the document is other than the default UTF-8 or UTF-16 and
 no encoding was determined by a higher-level protocol.

So even if it is not required, it is recommended. But yes, removing <?xml?> for bug-compatibility conformance is better idea than mucking with browser detection... if we sould need browser detection to avoid other bugs (like non-W3C CSS box model in IE), then perhaps we could reintroduce <?xml?> in standards-conforming browsers.
