Production note: X3D Object Model gets updated each time the X3D XML Schema is modified.  Also in version control.  Each at

http://www.web3d.org/specifications/X3DObjectModel-3.3.xml
https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/specifications/
https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/specifications/X3DObjectModel-3.3.xml

Further update: the changes above have been applied similarly to the X3D JSON Schema (thanks Roy).
