[x3d-public] Mantis? No SceneGraphStructureStatement AbstractNodeType present in old X3D3 versions, X3DUOM

[John Carlson]

I just discovered this draft.   Sorry for the delay.  I think the primary
goal should be the alignment of the statement type hierarchy between X3D3
and X3D4.

I’m wondering if my changes locally affected fieldValue.setIS as previously
reported?  Or fieldValue.addChild(new IS()) (IS is not a node)

I am thinking someone should look at the type hierarchy differences for
statements. If we go with X3D4, I will upgrade various examples.

I guess the other solution is to provide different jars for X3D3 versus
X3D4.
