So this is purely from an sXBL author's point of view?  I'm not sure I
uunderstand then.  When the XBL prebind event has been fired on the
element, you would add a DOMNodeInsertedIntoDocument listener on to it.
This might be problematic for the case where a previously registered
capturing listener on the document immediately removed that element, but
surely you could just check if it was still there if this mattered
(with, for example, Node.compareDocumentPosition).

I guess I don't see what is special about notifying the binding that the
bound element is inserted into the document.  To be inserted into the
document, it would have to be not in the document tree beforehand.  And
if that is the case, the binding may as well use the 'bound' event to do
whatever it needed to do.
