more than that...

yes and yes :-)

the neat thing is, syntax checking can be done by validating the .xml
file... and I'm sure someone will come with a GUI, once vcdimager-xml is
there, to create such an XML description in a graphical way...
I'll write one myself if I get the time for it, but anyone is free to
write one in the language and toolkit (s)he wants to...

I'm using libxml2 for the actual development...

well, to give you an idea, here's an example xml description...
(it's still a draft -- so it's not final yet!)
