I agree.  Code is malleable and this support can be added to X3DOM, matching Cobweb's achievement.

- an HTML script element is not the same as an X3D Script node

- Prototypes have been implemented many times in many ways (including InstantReality).  X3DJSAIL just had a fix for nested ProtoInstance nodes this evening.  Perhaps ProtoExpander pattern could be a preprocessor in X3DOM if considered onerous otherwise.

X3D is a content standard, not an implementation mandate.  Onward with X3DOM, Cobweb and X3D v4.

all the best, Don
