i use SVG in a similar way; as a 'template skin' for various aspects 
of my GUI.  right now i hacked a version of libsvg that allows me to 
'selectively render' parts of my SVG elements by turning elements off 
and on, but i also need a way to process SVG elements in my app, 
dynamically, so that I can for example say "make this SVG element X 
the same color as this SVG element Y", or copy 'broad attributes' 
from one SVG object to another, easily.

for now, i'm hacking the SVG DTD and libsvg render-system myself, but 
I'd love for there to be a more general-purpose "SVG attribute" 
modification API that I could use in C...

the other plan is, anyway, to put the python interpreter into my 
code, and just use python to do the SVG/XML parsing and handling .. 
this would be useful for other aspects of my app, but I'd reallllly 
like it if there were a more libsvg-style approach to doing SVG 
content creation/modification on the DTD ..

DL'ing spacewar now, too .. do you know how well it compiles on OSX yet?
