I had the impression that canonicalization (c14n? :-) ) as an
idempotent operation, that is, if you recursively apply canonicalization
to a name you'll keep obtaining the same result. At that point,
I think that it could be safe to add canonicalization both at
resolver and at server, so that even if one of those fails we get 
the correct result anyway.

ciao, .mau.
