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

[Holger Seelig]

The upcoming X3D4.1 specification defines a DESCRIPTION keyword for the IMPORT and EXPORT statement:

https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4.1-CD/Part01/components/networking.html#IMPORTStatement

Because the showed syntax looks like Classic VRML Encoding, I would expect to find it again in the draft grammar:

https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19776-2v4.0-WD1/Part02/grammar.html

Additionally I would expect to have a similar syntax (attribute for XML, a property for JSON) for the other encodings. 

Best regards,
Holger
