We aren't really worrying about the document structure at this time
(1st working draft) so N-Triples may be in a another document later.
Although N-Triples is a subset of Notation3, Notation3 is a different
semantic web research language, which is still changing, and the
authors are pretty friendly, so let them know.

We are considering the issues about making N-Triples using only UTF-8
encoding instead of ASCII - there are pros and cons, relationships
with XML Blueberry (since RDF is close to XML) and Notation3 to
consider.  This change will be in working draft #3 at the earliest.

I didn't change this since, as I note above, we might remove it.
