When I send this through a Jsonix mapping things work, but I haven’t validated the documents agains XSD yet.   Is there a reason why this is not used in X3D XSD?  Does it create a text node or require a text node?   It is highly likely that I will create a custom XSD and check it into my x3djson repository.  I am not proposing this as a modification to the XSD yet.  It requires more research and expertise.  There may be an alternate X3D XSD for working with JSON.  That is all.  Perhaps this has been done?

I’m not really sure.  Experts can tell.  This is already done for booleans, strings and time.   I’m not sure what the performance penalty might be, but I think we’d get a speed up in JavaScript.  It’s also time to think about typed arrays and how to smoothly integrate with them.
