This is one thing that I won't remove from Lisp.  For example, the 
format of URLs from Netscape/Mozilla has changed several times.  More 
and more new types are being added by Gnome and KDE file managers.  
Having the decoding of all that in Lisp is so much more flexible and 
much easier to modify, maintain and debug than having it in C.  If a 
general part is made, the decodings will be done in the platform 
specific parts, that's obvious.

I don't follow, what kind of action is text, URL, file?  An action 
would be more like insert-text, open-file or some such.

As it is part of the protocol in both XDND and Motif, it will not go 
anywhere.  I'll try to include some generalization of the concept.
