No.  I've looked.  Every mention of the "CLASS" attribute I've been able
to find in any archive only mentions its use as a stylesheet hook.
(except maybe for 
	<URL:http://www.w3.org/hypertext/WWW/MarkUp/html3/divisions.html>
which uses <DIV CLASS=APPENDIX> in an example).

The %cextra; and %pextra; extension parameters were 
present in the 5-Apr-1994 HTML+ DTD and disappeared sometime 
between then and the 9-Feb-1995 HTML 3 draft; the universal
CLASS attribute was not in that draft.

I was mistaken: user-defined semantic extensions appear not to have
been the motivation behind CLASS and it is intended only for 
stylesheet processing.
