Following other comments, we distinguish between Charmod Fundamentals (a
W3C Rec, and a normative reference) and Charmod Normalization (a W3C
Working Draft, and an informative reference).

Looking at
http://www.w3.org/TR/2005/REC-charmod-20050215/#sec-Conformance

there is a four point list of how to conform:

Specifications conform to this document if they:

   1. do not violate any conformance criteria preceded by [S],
   2. document the reason for any deviation from criteria where
   the imperative is SHOULD, SHOULD NOT, or RECOMMENDED,
   3. make it a conformance requirement for implementations to
   conform to this document,
   4. make it a conformance requirement for content to conform
   to this document.

After review, we believe that we already conform to point 1 and have
nothing to document for point 2.  We agree that we did not conform to
points 3 and 4 and have corrected this as follows:

For point 3, we added this to Conforming SVG Interpreters (thus also
covering Conforming SVG Viewers)

  <p>A <em>Conforming SVG Interpreter</em> must conform to all
  applicable 'I' conformance criteria in Character Model for the World
  Wide Web 1.0: Fundamentals [<a
  href="refs.html#ref-CHARMOD">CHARMOD</a>].</p>

For point 4, we added the following to Conforming SVG Document
Fragments:

  <li>Conforms to all applicable 'C' conformance criteria in Character
  Model for the World Wide Web 1.0: Fundamentals [<a
  href="refs.html#ref-CHARMOD">CHARMOD</a>]</li>

this also covers Conforming SVG Generators which are already required to
generate conforming content.

The paragraph from which you quoted an objectionable sentence now reads
as follows:

  <p>SVG generators are encouraged to follow <a
  href="http://www.w3.org/International/">W3C developments in the area
  of internationalization</a> such as Character Model for the World Wide
  Web 1.0: Normalization [<a
  href="refs.html#ref-CHARMOD-norm">CHARMOD-norm</a>] Future versions of
  the SVG specification may require support of that specification in
  Conforming SVG Generators.</p>

Björn, please let us know shortly if these changes do not resolve your
comment.

Richard, if you spot anything we missed, please let us know.
