Unable to parse VAST files

[gpaluk]

I am trying to generate a JSON file against the following XML and schema:

http://52.43.137.19/vast/vast_example.xml
http://52.43.137.19/vast/vast_schema.xsd

I am using Linux so I use the following command line call.

java -Djava.endorsed.dirs=lib/commons-io-2.4:lib/commons-lang3-3.3.2:lib/xerces-2_11_0-xml-schema-1.1-beta -jar sax2j.jar vast_example.xml vast_schema.xsd > vast.json

However, I receive the following exception:

Using XML Schema 1.1 to parse vast_example.xml Exception in thread "main" org.xml.sax.SAXParseException: s4s-elt-character: Non-whitespace characters are not allowed in schema elements other than 'xs:appinfo' and 'xs:documentation'. Saw '2.0'.

I am not sure where or not this is due to the XML spec being 1.0 or 1.1 etc, however I have tested the validity of both the XML and of the schema using online services which seem to imply that they are both correct and I checked that the XML passes the schema definition using those same online services. Perhaps someone here might be able to see what I am doing wrong or validate if there is some issue with the parser?
