This way the DEF names can be used even if they are identical across scenes. X3D semantics and functioning is not affected.

I think the SAI equivalent is roughly that all nodes are EXPORTed by default and that in addition to a DEF name it becomes possible to address a node by its path in the scene hierarchy. Perhaps something to consider for the standard: X3D selectors.
