<p class="MsoNormal">First of all, great work on x3d.py, Loren and Don, I feel like I am polishing a diamond. <u></u><u></u></p>

<div>
<p class="MsoNormal">I am considering adding the containerField attribute (not field) to XML output in x3d.py. This is mainly to support requirements of view3dscene. It complains if I don’t add the containerField attributes in HAnim (skeleton and joints containerFields, maybe more)—the default, children, is not an acceptable to view3dscene. Also, not having a skin containerField is weird when dropping arbitrary Shape nodes into a HAnimHumanoid. <u></u><u></u></p>

<div>
<p class="MsoNormal"><u></u> <u></u></p>

<p class="MsoNormal">Does adding the containerField attribute seem like a good idea, or should I push back on browser vendors?<u></u><u></u></p>

<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">I plan to do something like I do for VRML when printing out joints and skeleton fields etc. I won’t print out the containerField for obvious fields, i have a list of these somewhere…geometry, appearance, material, etc <u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">Should I allow the x3d.py app programmer to add a containerField attribute, or should I compute it as best i can, and save browser vendors the pain?<u></u><u></u></p>
