[x3d-public] X3dToJson.xslt changes for X3D JSON schema

[John Carlson]

If this is being reviewed for file size, I need a disability accommodation
to allow it.  Apparently I cannot communicate properly without images.

There are probably thousands of X3D archive that are wrong, they use a
string to represent an MFString instead of an array, including this one:

web3d.org/x3d/content/examples/ConformanceNist/Appearance/Appearance/ImageTextureChild.json
<https://www.web3d.org/x3d/content/examples/ConformanceNist/Appearance/Appearance/ImageTextureChild.json>

Here's a snapshot:

I am not sure about the green part of the patch below, but @transitionType
an X3D MFString that's an array in X3D JSON schema as well.  Please test
the patched X3dToJson.xlst with @transitionType.
My JSON files do not contain transitionType, so I haven't tested that with
X3D JSON schema.  What I see in the X3D JSON zip on X3D resources examples
is a string array for @transitionType.  Why is @transitionType rendered
differently than @type in the zip archive?

Here's an example that has the NavigationInfo @type as an array, not an
string:

Yet the stylesheet on sourceforge doesn't produce that, as evidenced by the
JSON in the first image.

I have a vision problem too.  It happens.

I think Holger will stand by me to say that all MFStrings in JSON should be
arrays, not strings.

The reason this is coming up is because I continually have to patch
X3dToJson.xslt for new changes to fix output.  I am considering switching
back to Holger's x3d-tidy, but the command line options are not as suitable
as I like for batch files, and I may fork it instead. So I can either
maintain my own stylesheet, or my own x3d-tidy.  I already have a working
stylesheet.

Here are changes to make NavigationType @type in X3D JSON validatable with
X3D JSON schema.
