HTML5 Drag-and-Drop Specification: dragenter

To whom it may concern:
The specification says that the dragenter event is "used to determine
whether or not the drop target is to accept the drop".  Do functions bound
to this event get any information about the object being dragged?  In
particular, is there a good way to have N drop targets, and have each of
them accept only certain draggables?  If not, it seems to me like a good
feature to have, especially as multi-touch applications/devices become more
prevalent.
Thanks.

Sincerely,
Jason Gross
