I'd suggest:

  (1) Make the alist entry be one of (DND-TYPE DROP-FUN TEST-FUN) or
(DND-TYPE . DROP-FUN) with TEST-FUN being a test function that accepts the same args as DROP-FUN. Putting the TEST-FUN last makes it easier
      to omit.

(2) If TEST-FUN is omitted/nil, default to some common formula like `in a
      writable text area'

(3) Export the default test-function as a real function, so the user can call it from his code too (or use it explicitly in the alist, though of
      course that would be redundant).

I see just one problem with this approach.  The DND-TYPE is not unique.
That is, when I drop a file from say the Gnome file manager, I have
several types to choose from, for example, text/uri-list, text/plain,
UTF8_STRING, and some more.  If a user is going to be able to make
an intelligent choice, I'd assume he wants to look at all acceptable
types as a group.  Also, there are several types out there that a user
can add to the alist that the current suggestion just ignores (say
application/xml or just about any unknown type).  How do we determine
which of these are more specific?

Am I missing something here?
