[x3d-public] 4 things before pursuing further development

*Bolded* is most important

Re: metadata containerField possible issues:

Here's the X3DUOM, bottom of *MetadataSet *ConcreteNode*,* AFAICT:

<containerField default="value" type="*containerFieldChoicesMetadata*"/>

Here's the SimpleType from above type:

       <SimpleType name="*containerFieldChoicesMetadata*"
                   appinfo="containerFieldChoicesMetadata lists the 
allowed containerField enumeration values for Metadata nodes: 
"value" if providing information and parent node is MetadataSet 
collection, otherwise default "metadata" if providing 
information about parent node."
          <enumeration value="*metadata*"
                       appinfo="this node provides metadata information 
regarding its parent node."/>
          <enumeration value="value"
                       appinfo="parent node is MetadataSet, this node is 
providing information as part of a MetadataSet collection."/>

So this shows to me that /metadata/ can be a containerField for 
MetadataSet. *I know why /metadata/ is not within MetadataSet.java 
alternate containerFields. * I will have to go back in email to figure 
out what data file I was using. In other words, I looked at X3DUOM and 
it looked okay, so I looked at the stylesheet, it looked like it didn't 
even used the above enumeration, just the default and some hard-coded 
stuff (under development?).  I understand the nature of taking time to 
apply patches.

I understand that I am having troubles communicating.  All I can do is 
try again, or give up, or take better care of myself.

At this point, I would welcome working with x3d.py instead of X3DJSAIL 
for HAnim.  See below.

*$ python JinLOA4.py **
**x3d.py package loaded, have fun with X3D Graphics!**
**Python-to-XML well-formed XML document  test of XML output successful**
**Python-to-XML X3D 4.0 schema validation test of XML output successful**
**Python-to-VRML export of VRML output successful (still testing)**
**Python-to-JSON export of JSON output successful (still testing)**
**python x3d.py load and self-test complete for JinLOA4.py*

Looking good.  Not so good my python code, which is based on X3DJSAIL. 
This has been discussed.

*Here are some file sizes from JinLOA4 examples in X3DJSONLD. Note that 
your python file size is approaching the uncompressed XML size. Woohoo!

Thus all my ditzing with my local sourceforge mirror has been undone.  
While I'm fixing it, you can finish your deployments.

> Thanks for your reports.  Once again, if you are building your own versions, you must use latest X3D DTD Schema and X3DUOM.  All dates are inspectable.  If we get those ground-truth versions fixed, all of the other changes are handled sooner or (sometimes) later.

I have updated my HAnim examples.   I need one meeting with Don and Joe to resolve issues beyond large code.  Notification of further changes to HAnim examples welcome.   Validators will be useful here.   JSON output from Java not currently feasible because there are warnings, even beyond large code exceptions.   We may also consider python HAnim, which run into the same problems as Java in my case.   I have not tried HAnim with Don’s python generated code much.
