[x3d-public] Comparing Joe*.* XML files

[John Carlson]

I get an XML file from the archives, for example JoeKick.x3d, convert to
JSON using X3dToJson.xslt and then convert back to XML using X3DJSONLD.
The I used xmldiff.js on the two XML files.  I get:

$ node ../node/xmldiff.js JoeKick.x3d JoeProcessedKick.x3d

Note that most of these are new containerFields, but there are perhaps
important differences earlier in the files.

The only approach that I see might work would be to include mapToMethod.js
in the JSON -> XML conversion. One might argue that containerFields may not
be required to render XML. One needs to examine how well mapToMethod.js
works in general.

Indeed, how are the JSON files themselves different?
