<p class="MsoNormal">Python does support multiple inheritance, but these fragments are not an example of a multiple-inheritance situation -- rather, the later class definition -- where _X3DField is a subclass of _X3DNode, overwrites the earlier class definition.

<p class="MsoNormal">So I think the operative question is whether it is a design intent that _X3DField also should be a subclass of _X3DNode. I judge the answer is no, since that would include support for DEF, USE, and metadata. In that light, the second class
defintion for _X3DField would be regarded as a bug, to be corrected by modifying the X3duomToX3dPythonPackage.xslt stylesheet.<u></u><u></u></p>
