[x3d-public] NIST conformance example behaviour

[Patrick Dähne]

Hello Andreas,

> What is an example where USE of a bindable node would be problematic ? A set_bind event would always go to the DEF node which is then bound, with all USE references following. The one currently bound node is still the DEF node since the USE references are not independent. The browser can in effect ignore all USE references of bindable nodes except for in scripts.

The rationale behind the rule „DEF/USE is forbidden for Bindable nodes“ is explained in The Annotated VRML97 Reference Manual:

(See the first tip in section 2.6.10.)

Bye,
