[x3d-public] Testing X3DJSAIL from NetBeans. IMPORTANT!

[John Carlson]

I think the issue here is the unvalidated scene graph.  That's why I 
write out the XML after loading with X3DJSONLD before I send it to 
X3DLoaderDOM.  My problem is, I don't know what to compare the 
intermediate XML with. What I will attempt to do is read in 
HelloWorldProgramOutputCanonical.xml and see if I get the same 
X3DLoaderDOM issues.

*** [X3DLoaderDOM error] Incorrectly handled X3DJSAIL object 
construction, current elementObject=LoadSensor (LoadSensor),

     This error can be caused by incorrect parent-child node 
relationships or incorrect containerField values.
     X3D node typing is strict, check or validate your scene graph!
     This error can also be caused by X3DLoaderDOM DOM omissions in 
X3DJSAIL. Please report mysterious problems, thank you.
