briefly... in working on IRI vs URI in the GRDDL spec,
it seems there's perhaps more that could be done...

I did some spelunking and found that both webarch and XML Schema
predate the IRI spec, and XQuery seems to cite XML Schema for xs:anyURI.

So I changed the formal occurrences to "IRI", but left many
of the informal occurrences as "URI", and added a note,
in the "Resource Descriptions" subsection of the intro, right
after we make the point about "unambiguous URIs"...

Note that GRDDL follows HTML 4, RDF, and XML Schema in using
Internationalized Resource Identifiers, i.e. IRIs[RFC3987]. While in
informal usage, this specification uses the more familiar term URI
interchangeably with the recently standardized term IRI, the formal
rules use the relevant terms precisely.

Norm also noted some XML Core work on "XML Resource Identifiers"
and noted that spaces are allowed in xsd:anyURI but not
in IRIs. That belongs in a test suite somewhere.... are
there XQuery tests for spaces in namespace names?
