In what way would the XHTML 1.0/1.1 spec **disallow** the use of this
element from the xml namespace? It's not *part of* the spec, but that's
a different matter, right?
I've been told is that xml:base should work just fine in Firefox, Opera
and other XHTML-capable browsers, when content is served as
application/xhtml+xml.
OTOH, for this message I decided to do a little test. The following will
be served as true XHTML by my server:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<title>Testing xml:base</title>
<style type="">
div#msg {
background: pink;
padding: 2em;
text-align: center;
font-size: xx-large;
}
</style>
<xml:base href="http://dev.keryx.pad/xhtml/css/"; />
<!-- link to my test server -->
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div id="msg">Pink background if <xml:base>
is not supported, otherwise light green</div>
</body>
</html>
In the external CSS I have:
div#msg {
background: lightgreen !important;
}
div#msg:after {
content: " - <xml:base> works! External CSS recognized.";
}
When I try this in Firefox 2.0 it does not work, nor will it in Opera 9.10.
It may be that I've implemented this in the wrong way - corrections are
welcome - but it seems to me that even though <xml:base> is legal today,
it is **not** supported by UAs. Which makes Anne's proposal, that <base>
should be allowed in both serializations, even more important.
