I think I agree, but that last sentence is potentially very misleading. 
  If the IRI is embedded in an XML document, the IRI's Unicode 
characters should appear in the infoset as themselves and *only* as 
themselves unless they IRI/URI-special characters like '#' or '%', in 
which case they should appear *only* as %-escapes.   In the XML 
instance, this may be accomplished by having them appear as themselves 
(if you're using an encoding that supports them) or via NCRs.

In the XML context, other mechanisms such as \u or base64 should not be 
used.

Right?
