Patching Metaschema (XSLT M4 implementation) datatypes with new definitions

[wendellpiez]

User Story:

Datatype support in the XSLT M4 Metaschema implementation needs to be updated to conform to latest work, so that XML and JSON schemas for OSCAL can take advantage of new definitions.

The work is being tracked in usnistgov/metaschema#191. New datatype definitions there must be integrated into the M4 pipeline.

This will also help address issues #1127, #1132, and #1105.

This Issue addresses changes supporting OSCAL 1.0.3, not a more thorough refactoring for 1.1.

Goals:

Capture new improved work on datatype definitions in schema generation from XSLT M4.

Dependencies:

New datatype definitions must be stable.

As advised by @david-waltermire-nist , work proceeds in WIP branch: usnistgov/metaschema@develop...wendellpiez:issue181-tokendatatype

JSON Schema and XSD look good so far.

@david-waltermire-nist let's review, as I think this work might be ready for integrating. Certainly worth looking at.
