Dale,
The talk at Xtreme 2000 made it, as I recall, quite clear that imbedding
anything in SVG left each activity separate.  I don't recall that any
modification to XTM would be required in order to imbed it inside SVG.
Graphical representation remains quite separate from knowledge
representation. Your humble opinion is shared by nearly everyone I have
talked with on this matter. My hunch is, however, that SVG would need some
reference into XTM in order to handle mouse clicks, but references to SVG
from XTM would not be necessary. I hope that I have been able to clear up
the notion that there exists any entanglements between XTM and SVG.  The
marriage of SVG with XTM seems to make sense, and will likely continue to do
so until I actually code it up and try it.
