[x3d-public] ECMAScript 6 X3D API

I ran into a problem with scenegraph conversion, converting force.json to force.mjs. Running force.mjs with node.js in the X3DJSONLD/src/main/node/net/ecma/data folder revealed a coding error where field arrays are not being closed off soon enough. The code to create the .mjs file is in …/node/ECMAScriptSerializer.js, but mjs are generally created with the X3DJSONLD/src/main/shell/several.sh script running like
$ bash ./several.sh ../data/force.x3d
I might start with the serializer, perhaps in a bit.
Another thing I might do is resort to Is something that follows the SAI Standard. I already have some code there, but it pretty much requires running in a browser to test.
Which seems weird, since EAI has been converted to SAI, AFAIK.

That is a major problem that may or may not affect X_ITE, but in my testing, I couldn’t see that any clicking worked.

The move to JSON Schema 2020-12 was not well informed as Ajv does not currently have a web solution, and the python validators are slow or don’t work. I believe that the Java solutions may be adequate, but the ant script in x3dschema repository does throw warnings I believe.
