[x3d-public] Forgot what we did Re: ProtoInstance for material in X3DUOM.

[John Carlson]

I forgot what we did to support ProtoInstance under X3DMaterialNode under Appearance.  I don’t see much support for ProtoInstance in material fields in Appearance in X3DUOM.  Is it valid to have a material which is a ProtoInstance?  I need some way of generating it in the JSON schema from X3DUOM.

See attached files.  Also, run the X3D file through X3DJSAIL and see if it produces similar JSON.  I see two differences (ProtoInstance is in an array, containerField is -children instead of -material), but my serializers may be off.

$ node ../node/jsondiff.js X3dHeaderPrototypeSyntaxExamples.json X3dHeaderPrototypeSyntaxExamples.new.json

r","@value":[0.2,0.6,0.6]}]}}]

Related Java:
              .setMaterial(ProtoInstance2 = new ProtoInstanceObject().setName("EmissiveMaterial")))

See, containerField is material. However the ProtoBody has two children, the first is a comment, so -children may be correct???

Rescue me from my confusion!
