How about this?

Function called for the return value of `x-begin-drag' when dropping on a frame.

It should accept two arguments POS and ACTION, and return a symbol
describing what to return from `x-begin-drag' if the drop happens on a
frame.  POS is a mouse position list detailing the location of the drop,
and ACTION is the action specified by the caller of `x-begin-drag'.

If nil or a non-symbol value is returned, the drop will be cancelled.
