I was pretty sure that attachEvent was copied to a clone in IE, although the rules you mentioned above would seem to indicate that it shouldn't be. Cloning various form elements also varies, although perhaps those are attribute-vs-property issues. If so, then it's counter to most people's expectations.
Perhaps the spec thinks it is clear, but these questions come up over and over again so I'd say the spec is too subtle.
