[x3d-public] X3D4 Architecture validation and implementation update, with thanks

[Don Brutzman]

John, thanks for thinking about this.

Annex L does not require or prohibit any specific capabilities, but rather provides guidelines for how things can work together.

HTML + JavaScript + CSS has a well-specified body of work describing capabilities and requirements.

Encouraging interoperability seems like the best path forward - hard to argue with good practices.

Whether further features in different browsers and codebases emerge is always possible - our maximizing regular, predictable content seems like the best path forward.

Have fun with X3D4!
