I second this.
I think that some documentation high-level enough
for low-education pointed-hairy boss (PHB) would be
a VERY good thing to sell SVG as a viable programming tool
as an applicable industry standard.

Also while you may use any tool to generate Use Case,
such as Rational Rose, take screen shots and save them as PNG,
you might also want to use SVG to represent them! =P

A simple perl script and an XML parser
with few parameters can easily generate
and calculate such diagrams.

If you edit manually, you might find EASILY
why the shortcommings with producing SVG diagrams
for UML and documentation purposes !

Especially, the layout area and connectivity between elements.
