tree annotations

[Guido.Bosch@loria.fr (Guido Bosch)]

I want to annotate trees of a given formalism F with a Lisp symbol, or
more generally, with any kind of lisp data structure. I also need this
data be saved and restored using the polish postfix format.

This data will never be used by Centaur tools (such as the ctedit
pretty printers).


The example that is given in the VTP manual suggests to extend the
formalism itself, but I think this is much too complicated for such a
simple purpose. Isn't there an easier way to do what I want?

There also seems to be a misspelling in the documentation: 
(The Virtual Tree Processor, p31.)

 > 
 >    This last decor can be used to annotate any tree, T , of F with a comment
 > tree, C, i.e., with a tree belonging to the phylum named COMMENTS:
 > 
 > 
 >       ({tree}:adopt T C ''comments'')
                           ^^^^^^^^^^^^
				
	                    "comments"


Thanks for any suggestions
