Hi Paul,
I have been a bit slow on the uptake, but I am beginning to
understand what are going on about.

OK, I think this could be done quite easily if we slightly improve the
revision attribute like this
<c/p revision="R2,R2"> the text</>
where R1, etc., would be one of the following variants
+n -- this fragment was added in revision n
-n -- this fragment was marked for deletion in revision n
!n{new_props} -- the formatting of this fragment was changed in
revision n, and new_props should be applied over the
normal properties held in the props attribute (new_props
would be just a standard XML property string as used by
props).
To illustrate with an example, you might have
<c props="font-family:Times New Roman" revision="!1{font-
family: Bookman}">some text</>
meaning, in revision 1 the formatting has been changed from 'Times
New Roman' to 'Bookman'.
I will redesign the PP_Revision class later today to parse this type
of an attribute.
