RDF C14N Comments

An easy binary choice is whether the C14N for xml-literals should preserve
comments or strip them.

e.g. given the following RDF/XML

<rdf:Description
  xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  xmlns:dc="http://purl.org/metadata/dublin_core#"
  xmlns="http://www.w3.org/1999/xhtml"
  rdf:about="http://example.org/papers/paper1">
  <dc:Title rdf:parseType="Literal"><!-- Relevant text start. -->
    Foo<em>bar</em>
  <!-- Relevant text end. --></dc:Title>
</rdf:Description>

Is the generated graph:

<http://example.org/papers/paper1> <dc:title> "<!-- Relevant text
start. -->\n    Foo<em xmlns="http://www.w3.org/1999/xhtml">bar</em>\n  <!--
Relevant text end. -->" .

or

<http://example.org/papers/paper1> <dc:title> "\n    Foo<em
xmlns="http://www.w3.org/1999/xhtml">bar</em>\n  " .

C14N allows both forms, and the RDF Core WG should decide which (or decide
that RDF applications decide which).
(Note I have used exclusive C14N with an empty InclusiveNamespaces Prefix
List).
