Simple. Canonical XML knows nothing about XInclude.  (Actually, it's 
based on XPath 1.0, which also knows nothing about XInclude.)  When a 
canonicalizer is presented with a document in which some elements 
look like <xinclude:include href="someURL"/> it treats these elements 
exactly like it treats any other element.  It associates no special 
semantics with them. It most definitely does *not* resolve XIncludes.

You may, perhaps, choose to resolve the XIncludes in document A, thus 
producing a new document B.  You may then canonicalize document B. 
However, what you get is *not* the canonical form of document A.  It 
is the canonical form of the new document B.  (These would only be 
equal in the trivially uninteresting case where document A does not 
contain any XInclude elements.)
