Doug, I don't know if you are familiar with my website, but I have been 
deploying inline SVG on pages for quite some time now.  In any case, 
there are some real issues that need to be worked out.  Examples include 
what <![CDATA[ ]>> means, and how tags like <script> are handled by SVG 
unaware browsers.  (Possibly <title> too, but that turns out to be less 
of an issue).
