No, it's about a situation where an element in the document has multiple
attributes that are recognised as 'class' attributes by CSS. (CSS doesn't
define what determines a 'class' -- or 'id' -- attribute, but leaves that up
to the document language(s)).
Actually, there is a way you can get this now, if we permit XHTML2 attributes
on XHTML elements:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:xh2="http://www.w3.org/2002/06/xhtml2/"
xml:lang="en">
<head>
<title>Virtual Library</title>
</head>
<body>
<p class="foo" xh2:class="bar">This paragraph has classes 'foo' and
'bar'.</p>
</body>
</html>
Assuming that it's valid for an XHTML1/XHTML2 UA to interpret the XHTML2
attributes on the above XHTML1 document -- something that's far from clear
anyway -- then all the original paragraph is saying is that a CSS-compliant
processor must apply class selectors as if the class definition was
something like <p class="foo bar">.
