<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.
<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">In the x3d.py file, only three classes
are defined as direct subclasses of object:<o:p></o:p></p>

<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.<o:p></o:p></p>
