To me, the following are the most useful things about XIncludes which are 
lacking in EPEs:

1) the ability to include only part of the referent, through XPointer.
2) the ability to include the other document as text.

I have found these very useful in practice.  I don't always have control over 
the document I'm including, so the ability to select only in part can be very 
important.  And as one who writes many articles in XML form, the ability to 
include external listings, and have them all escaped for me on inclusion saves 
a lot of work.
