        I would suspect that you have either not informed
the
Canvas that the document will be dynamic (search for
ALWAYS_DYNAMIC), 
or you are not making your changes in the UpdateManager
Thread.

I don't know if this is the problem, but the code I use to
do this passes 
"href" as the attribute, rather than
"xlink:href". You're effectively 
setting the namespace twice -- maybe that comes out to
"xlinklink:
href" 
in the DOM.

I also have

    xmlnslink=
"http://www.w3.org/
1999/xlink"

in the top-level <svg> -- just in case you're missing
that.
