    <!-- Purpose: Produce a JSON Schema reflecting constraints defined in a metaschema -->
    <!-- Dependencies: This is a 'shell' XSLT and calls several steps in sequence, each implemented as an XSLT -->
    <!-- Input: A top-level metaschema; this XSLT also composes metaschema input so composition is not necessary -->
    <!-- Output: A JSON Schema (v7) describing a JSON format consistent with definitions given in the input metaschema -->
    <!-- Note: This XSLT uses the transform() function to execute a series of transformations (referenced out of line) over its input -->
    
    <!-- Debug variant writes out JSON Schema as XPath XML subject to validation -->
    <!-- Check its fitness for serialization by validating against XSD ../../support/xml/xpath-json.xsd -->
