This is not to be considered final in any way. This is an exercise used in the prototyping of potential JSON serializations of CCTS documents by converting their XML to JSON syntax.
Use the following invocation:
saxon9he -xsl:CCTSXML2JSON.xsl
{+gc=UBL-Entities-2.1.gc}
-s:inputXML
-o:outputJSON
The +gc= argument is optional. When supplied, the
program leverages the type information available in the model definition
as required by BDNDR 1.0.
Without such information, the serialization uses anonymous typed content
and preserves the attribute names from the XML (which are assumed in all
cases to have been pre-validated with project schemas) as required by
BDNDR 1.1.
The output is simple text without XML escaping.
indent select="'yes'" as="xsd:string" (xsl:param)
The output can be indented if desired; set to "no" for continuous
extension-content-regex select="'^Extension.*$'" (xsl:param)
The name for extension content
gc as="document-node(element(gc:CodeList))?" (xsl:param)
The CCTS dictionary is expressed as a genericode file of properties such as the example for UBL found at http://docs.oasis-open.org/ubl/os-UBL-2.1/mod/UBL-Entities-2.1.gc.
When this file is absent, the serialization presumes the use of CEFACT Unqualified Data Type attribute names and anonymous-typed content.
c:BBIEbyName match="Row[Value[@ColumnRef='ComponentType']/SimpleValue='BBIE']" use="Value[@ColumnRef=('ComponentName','UBLName')]/SimpleValue" (xsl:key)
Keep track of each BBIE by its XML element name in GC file
