> What else do *you* need?
Process improvements. Your asking 'what else do you need?' is a process
step I haven't explicitly seen before, I think that's a good step.
There could be 'CALL FOR's that notify sleepy browser / tool makers to wake
up on a topic and contribute before some regrettable decision is baked into
specifications. CALL FOR NEW FEATURES 2 years before next draft would allow
browser / tool developers to compare notes in a PRE-DRAFT and list new
features and nodes, and give 2 years for other browser / tool developers to
implement. Then each implementation is noted on PRE-DRAFT to see which ones
have traction. (versus last-minute scramble to find a second implementation
or ignoring that PROCESS REQUIREMENT while writing draft specification).

> Extensibility mechanisms for X3D can implement new capabilities
I find PROTOs awkward and find it easier to implement new builtins. A CALL
FOR PROTO DESIGN PATTERNS, EXAMPLES AND ANALYSIS OF PROTO SYSTEM
SHORTCOMINGS, AND EXTENSIONS TO EXTENSIBILITY could expand web3d power and
attractiveness
Design patterns - I'm thinking of how to design builtin nodes so as to make
extensibility easier. A CALL could bring forth examples of builtin nodes
that don't map to a PROTO implementation, and analysis of those
shortcomings may produce design patterns to improve current PROTO mechanism
and suggest new extensibility mechanisms / extensions to extensions.
