It is, but that isn't the smallest possible diff for that document type,
which could be generated by some magical xmldiff like one of these:

        http://www.logilab.org/projects/xmldiff/
        http://apps.gotdotnet.com/xmltools/xmldiff/overview.html
        http://software.decisionsoft.com/tools.html
        http://forge.nesc.ac.uk/projects/xmldiff/

all of which provide a context sensitive diff, based on the underlying
XML structure. The binary diff algorithm doesn't know nothin' 'bout
parsin' no XML files, so it is just a binary mapping between two
collections of bytes.
