Hi,

Right, I specified that use case to answer to the message of  Double
Y.(http://lists.w3.org/Archives/Public/www-svg/2003Feb/0055.html).

This is a part of our work but not the only one. We are working in all which
is related to the content adaptation and negotiation problem in
heterogeneous environments
(http://opera.inrialpes.fr/people/Tayeb.Lemlouma/NAC.htm,
http://opera.inrialpes.fr/people/Tayeb.Lemlouma/publication.html) and to the
Device Independence problem (http://www.w3.org/2001/di/).

Sure, if we see the markup biniarization independently to its use in a
specific protocol, it can always be useful by applying efficient methods and
for different applications (compression, etc.)

You got the point. Personally I don't know any effort proper to SVG, this is
an interesting problem to see if a specific binarization of SVG can be more
optimized than existing XML binarizations.
