This has worked in X3DJSAIL, AFAIK. I don’t know about output from X3DPSAIL yet. I believe that X3DJSAIL also offers .addComments() methods to add CommentsBlock instances to the scenegraph, in many classes. I would primarily like this feature in order to do round-trip testing back to XML. Obviously there’s a whole discussion whether we should be converting XML to Java and Python. That’s how I create Java and Python test cases. Don prefers hand-coding tests, I think, and probably feels he is serving the programming community. I feel we have 4000+ XML examples that serve an excellent proving ground. Plus, I also have my own tests for my JSON loader I create from XML.</span></div><div dir="auto"><span style="font-family:-apple-system,sans-serif"><br></span></div><div dir="auto"><span style="font-family:-apple-system,sans-serif"><div style="font-size:inherit"><div dir="auto" style="color:rgb(0,0,0);font-family:-apple-system,sans-serif;font-size:inherit;font-style:normal;font-weight:400;letter-spacing:normal;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;text-decoration:none">Ultimately the above will be critical if we wish to output comments using the XML(), VRML() and JSON(), etc. methods in X3DPSAIL to produce documentation inside the scenegraph output.
