For me at least, the key issue is whether the atom:updated time has changed 
(what RFC4287 considers a significant update). However there would have to 
be a content change too (replacing the content with "this entry has been 
deleted" would do it). New child elements wouldn't make any difference.

Well there's the "Updated Conformance Test" on the Atom wiki. It's not a 
very good test, but I suppose it's something.
