Well, I think that for XML::DifferenceMarkup, canonicalization would be better 
than assertions - I want to ensure the whole DOM of my diff is as expected, not 
just parts of it. OTOH it's another step which can fail (especially as it's 
using an extra executable)... Is it possible to compare trees in XSLT?
