Christoph,
The standard allows for custom navigation extensions (see
http://www.web3d.org/documents/specifications/19775-1/V3.3/Part01/components/navigation.html#NavigationInfo,
15th paragraph -- starts "Browsers may create..."). Some features may be
prohibited or not explicitly allowed. The second case allows for
features that are not in the spec, but not explicitly prohibited either.
