writing once xml is not a problem... it's reading it later and trying
to amend it that is really painful.

If I was crazy, I would use C++ and a compiler as the parser, filling
a scene object with other objects... a rendering would be the
interaction of a camera with a scene. The only problem I would
foresee: the dynamic generation of code ... you know, the first part
of the parsing generate an include file to be included later... but do
we really need that ?(I'm afraid someone will want it).
Animation ? well, just a matter of looping...
Povray 3D objects, and all others aspects, just a library within a
dedicated namespace.
usual functions : just native coding.
Remaining problem: new users have to learn C++ and get a C++ compiler,
linking with the povray library.
Povray::Torus obj1(1,0.1);
// texturing can be a post constructor operation
Povray::Cone obj2( Povray::3DVector(0,0,0), 1, Povray::3DVector(), 2);
Povray::Scene take1;
take1 += obj1;
take1 += obj2;
