It is a validation error if there are duplicate IDs
in a document.

True, and this would be a validation error.  The same is
true if you used external parsed entities.  XInclude does
nothing to solve the ID uniqueness problem.  

In particular, if you reuse the same chunk of XML in two places 
in the same document and any element therein contains an ID, you
will end up with a document that is not valid (whether you
use external parsed entities or XInclude).

Maybe, but that isn't how things work in XML.
