I just remembered that we discussed this last year; see the thread
starting at
http://lists.w3.org/Archives/Public/www-dom/1998OctDec/0330.html .  At
the time, we concluded that no reasonable meaning for == could be
chosen, and if a future DOM Level N draft specifies some different
behaviour, we're in trouble, so it would be best to have a completely
different method for such comparisons.

	So, how about isSameNode()?  node1.isSameNode(node2) returns
true iff node1 and node2 refer to the same underlying node in the
tree.

Returned to his place, he sits quite still, pretending he doesn't exist, which
is a harder game than you might imagine.
