Why do you think this? Can you give an example of how you see this
working when somebody just wants to replace a menu path or something? It
seems like a lot of overhead to me when compared to the solution I
outline below (at least, every XInclude solution I have attemped to come
up with to this problem has been more awkward than the below for small
replacable portions....)

I am not sure what the full range of things that need to be changed are
(Patrick, have you guys worked out a roughly complete list?), but this
is a problem where I think entities work better than XIncludes.

In my day job, we have exactly the same problem: user guides and
(particularly) testing documents for various of our products are
customised on a per-client basis; the documents themselves are in
DocBook. We have a file for each client containing entity definitions --
each entity must have a value appropriate for that client. Then the main
document includes the entity file as a parameter-entity reference in the
DOCTYPE declaration and never needs to be changed. Filling in the entity
file for a new client is tedious but not brain surgery -- in fact, we
generate it from a slightly more readable format using a line of sed in
the Makefile.

Note, also, that the parameter-entity method works transparently if you
are XIncluding other documents (i.e. it is not an either/or choice): you
need to include the PE reference in each document's DOCTYPE, but there
are no double-definition problems or anything.
