No, it doesn't automatically document anything. A string of ASCII 
digits, spaces, signs, and dots is not document. It's as obscure as any 
other format.

No. Have you even worked with Maya, Blender, or any other 3D animation 
tool. Nothing is out of range because you can hand-edit curves and 
individual points in those tools.

Yes, really.

Digits of precession. Most people don't even think of putting enough in. 
There is also the human tendency to round things to "nice" numbers.

X3D does not handle FBX. FBX is the standard interchange file format for 
models, animations, rigging, textures, etc.
