[x3d-public] X3D Specifications ready for review: XML, ClassicVRML, and Compressed Binary Encodings

[Don Brutzman]

thanks John.  next three standards will be EXI, JSON, and Turtle.

are still stuck on 2022 draft IETF RFCs, not sure why.

   - https://json-schema.org/specification

all the best, Don
