<p class="MsoNormal">Thanks for reports and correct diagnosis. I did take out the three “object” inheritances earlier today, pylint says it is no longer required in Python 3, no ill effects noted.<o:p></o:p></p>

<p class="MsoNormal">Sure enough, searching for “class _ X3DField” in x3d.py reveals two abstract class definitions, ouch! That’s more like multiple personalities that multiple inheritance…<o:p></o:p></p>

<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>

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

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

<div>
<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>
