[x3d-public] -textureTransform -children fails to validate

[John Carlson]

Roy,

The following JSON fails to validate, I think, at this point:

                      "-textureTransform": {
                        "-children": [
                          {
                            "#comment": "NULL node as child"
                          }
                        ]
                      },

Likely more work needs to be done on the JSON schema and SFNode node fields.  I believe this is how you told me to do it this morning, so please advise.  Note that this is version 3.0, but I am validating with 3.3, I hope, it’s hard to tell, I cleared the 3.0 schema out of my browser.  It would probably be best if you validated against 3.3 yourself.  The error report failure is popping up (-children is an unexpected additional property), so…

Thanks,

John
