Making runtime lapses noisier / improving checks

[wendellpiez]

User Story:

In some conditions of not-yet-ready, metaschemas currently give misleading error messages from the Schematron - for example, if an assembly is defined but not used, the Schematron can report errors for its child definitions not linking up, when it is the parent that is not linked yet.

This is easily enough checked by generating an XSD and finding in it comments showing where definitions have been dropped (that were never called).

Here is a micro-metaschema that demonstrates:

issue80-micro-metaschema.zip

Goals:

Two possible improvements here:

1. Refine metaschema check or error message to find the bug better
2. Make schema generation 'noisier' (both XSD and JSON Schema production) about definitions not included - xsl:message with a parameterized switch to turn on?

Dependencies:

This is a good issue for someone who wishes to dip into the Schematron and XSLT and modify them, but who wants to avoid a deep exercise in analysis or refactoring.
