[x3d-public] JSON parsing X3D archive, X3dToJson.xslt issues.

[John Carlson]

XmpMetadataEmbedded.json:

                 { "MetadataSet":
                   {
                     "@name":"namespaces",
                     "-metadata":
                       { "MetadataString":
                         {
                           "@name":"xmlns:rdf",
"@value":["http://www.w3.org/1999/02/22-rdf-syntax-ns#"]
                         }
                       },
                       { "MetadataString":
                         {
                           "@name":"xmlns:dc",
"@value":["http://purl.org/dc/elements/1.1/"]
                         }
                       },
                       { "MetadataString":
                         {
                           "@name":"xmlns:xmp",
"@value":["http://ns.adobe.com/xap/1.0/"]
                         }
                       }
                   }
                 },


Appears that -metadata: is not an array, as perhaps it should be?   What 
do you think? I believe X3DUOM says SFNode for -metadata.  No 
containerFields come into play from the XML, as far as I can tell.  
Perhaps there should be some containerFields that use "value" as a 
container field name in XML? Or should we change X3dToJson.xslt to go 
along with possible X3dToJava.xslt moving up "addValue" or use default 
containerField as value.

SplitChannels.json:

Two Materials next to each other when there only should be one in XML.

SpatialAudioCameraAnimation.json:

Error is similar to SplitChannels.json error.  Found in XML prior to 
conversion to JSON.

ScannerMetadataExample33.json:

Two -children: [] arrays below Scene.  "Appears" to be an issue with 
X3dToJson.xslt

Will report on Savage after redoing parsing.
