I noticed this Pace doesn't mention canonicalization, and from what I 
can tell, RFC2396bis section 3 leaves room for variety in how a URI may 
be formed.  Shall we add language similar to that found in section 3.6 
(identity constructs), specifically 3.5.1 (recommended normalization 
strategry) and 3.6.2 (character-by-character comparison)?  We could 
also simply refer to those sections and say "follow the same rules".
