Usage: ${BASE_COMMAND:-$(basename "${BASH_SOURCE[0]}")} METASCHEMA_XML OUTPUT_DIR SCHEMA_NAME [ADDITIONAL_ARGS]

Produces XML Schema (XSD) and JSON Schema from Metaschema XML source, using XML Calabash invoked from Maven.

SCHEMA_NAME specifies the prefix output files will be written to, for example:
    a-metaschema -> a-metaschema_schema.xsd, a-metaschema_schema.json

Additional arguments for XML Calabash should be specified in the 'key=value' format.
