Yes, those are all valid in HTML 4.01. @class contains a
whitespace-separated list of CDATA items. The definition of CDATA for
HTML 4.01 is as follows:
CDATA is a sequence of characters from the document character set
and may include character entities. [1]
Unlike @id and @name, @class appears to be completely unrestricted in
HTML 4.01. However, when using XHTML, you must remember that the
definition of CDATA is governed by XML. The XML grammar specifies
that character data (CDATA) is specified by the following grammar
declaration:
CharData ::= [^' [^'. [4]
I hope this helps!

ratification of C++0x, and the day that I can code without logic
troubles.
