- I'm not convinced that parsing arbitrary sequences into *IRIs* is 
indeed required

- I'm also not sure about the requirement on "normative algorithms"; 
maybe we can clarify what qualifies as such.

It has done so for many years (unless this is about an IDNA/I18N aspect 
I'm usually try to stay away from :-)

Not sure what you mean by "base URI referencing".

The URI spec defines resolution already, and the algorithm it uses can 
be applied to IRIs as well. Furthermore, it doesn't depend on knowledge 
about whether a scheme is hierarchical or not.
