That obfuscates a bit.  I suggest that flat and hierarchical NP post-
modification are both legitimate treatments of 'the printer on the desk
in the office at the end of the hall', and that DIPETT at the moment
with its conj_pps(implicit_and) structure is predisposed to the flat rep.
We are all in agreement that we need to be able to move PPs out of this
structure as delivered by DIPETT, into one where they can modify a Case
marking prep's entity object as a post-modifier.  But we may not want to 
allow the user to nest PP post-modification below this one level, ie to
enforce the flat rep.  Or we may allow it, in which case the user will 
have to intervene more often, given the starting point of a flat conj of
_pps (a more dscriminating rep requiring a more discerning user). 

This might be a good point to introduce a theme that was brought up a 
year ago and which Sylvain touched on earlier today--correctness.  As I
recall, people last year thought that the reattacher should not be able
to produce wrong trees, ie the functionality to do so not be implemented.
I think we need to decide whether we will allow PPs to modify each other
to indefinite depth or not.

Tokens were put in only to facilitate user interaction.  Will you be 
interacting with the user to the point where you'll need to show phrases?
