Christine,

And here is another idea but only usable when the edit traces are bound to xml elements (or PI's) in the text.
Advantages: no scripting needed and user can use the normal print command

How?
Change the style definitions for the elements/PI's to call a xyperl function that keeps track of the starting and ending page positions of each edit trace. The xyperl keeps on writing the page positions found into a file.
When compose is done you will have a file that contains all the page positions that contain edit trace.
And guess what: the -ip option does support calling a file with page positions that you want to print.
So for your users it is just a question to add something like -ip ./pagelist.txt to the print command.

The downside of this approach might be that you will need to do a full compose in order to make sure that your pagelist file contains the correct list of pages.
So for an environment where you do heavy interactive touchup of a division this might not work....

And I am sure that there are even other ways you can arrive at the same result...
