[x3d-public] X3D JSON Schema warnings and validation automation progress

[John Carlson]

Cool.  Good work Don.   I reported earlier that schema validation was integrated into my X3D JSON Loader, if you don’t want to have to bother with uploading a schema. http://coderextreme.net/X3DJSONLD/ <http://coderextreme.net/X3DJSONLD/>  Recent additions include adding encoding and version from JSON to XML.  I currently use the Ajv schema validation suite which reports different errors than json-schema-validator.
