Graphml elements for "Open Group" Properties

Question

I'm looking for the Graphml elements equivalent to the yEd properties for "Open Group" in the Properties View.

Especially for the property "Nesting-dependent Shading"

Answer 1

Create a simple diagram with one group node only, save as GraphML with "Nesting-dependent Shading" enabled and with shading disabled, and compare the two GraphML files in a (text) diff tool.

Thank you very much for your hint.
I found the groupDepthFillColorEnabled="false" element within <y:State .../>

:

           <y:GroupNode>
...
              <y:State  .... groupDepthFillColorEnabled="false" ... />
...
          </y:GroupNode>
