The format has been published. I'm not sure of the official details,
but one of the Inventor team on this list should be able to elaborate...

Since VRML is a file format, not a development library, I merely offer
Inventor as a suggestion for file format. Inventor doesn't have to be ported
to every platform in order to use the file format. The viewer just needs to be
able to parse it.

the exact reason why I prefer it over OOGL which seems similar to
Inventor, but not as well-documented or accepted.
