Yes, we have conceptualized it as akin to macro expansion.  Which is OK as far as it goes... but X3D Specification also allows nested prototype instancing and even nested prototype declarations.  Furthermore, authors might well pursue dynamic modifications at run time.

So X3D is definitely Extensible, and achieving that is one of the most challenging features for any programming language.

Yes javascript certainly does have a rich (and growing) set of design patterns that might inform and be applied as we continue to enrich the X3DOM and Cobweb implementations.

all the best, Don
