You are welcome to do anything with Javascript and Node work within X3DJSAIL and we can ensure documentation/examples remain current.<br>

I have not done anything (maybe ever) with that stylesheet.

As before, the central issue driving everything else is defining examples for X3D SAI JavaScript/EcmaScript programs that can run standalone in Node.js. Until we get clear on that, have no way to assess whether any other work is adding value.<br></blockquote><div><br></div><div>Yes, repeat, sorry:</div><div><br></div><div><a href="https://github.com/coderextreme/X3DJSONLD/tree/master/src/main/node/net/coderextreme/data">https://github.com/coderextreme/X3DJSONLD/tree/master/src/main/node/net/coderextreme/data</a></div><div><br></div><div>All my NodeSerializer.js examples.

Hoping to get clear on that, what does end result look like.
