This makes sense to me. Notes have dated and short names.  For the
purposes of promoting Turtle in HTML, Turtle can have a very short
section which references e.g. <http://www.w3.org/TR/rdf-in-html/>.

We'd want to have a dated version before the end of PR, e.g
  http://www.w3.org/TR/2013/NOTE-rdf-in-html-20130415/
and we can write further editions as we learn and think more. I
propose rdf-in-html insted of data-in-html presuming it would talk
about the interpretation of RDF dialects and named graphs and that
sort of thing.
