You probably want MathEngine Karma for PS2.

This is one of my favourite subjects - declarative formats for physics.
Another alternative could be to go for Modelica, which is an open and well
structured language for multi-physics, but it might be overkill for ODE.
MathEngine/Critical Mass Labs has defined a DTD for defining things in 
XML, and
that works just fine with Vortex.
I strongly object against VRML/X3D (not the format really, but the 
organisation!)
and I think this subject this is far off-topic for the W3C.
I'm not sure if Critical Mass Labs consider their XML format to be 
proprietary
or open.
