Implementation Notes

SHACL Test Suite Failures:

- core/property/datatype-ill-formed.ttl : Waiting on RDFLib support for determining ill-formed Literals https://github.com/RDFLib/rdflib/issues/848
- sparql/pre-binding/shapesGraph-001.ttl : Prebinding to $shapesGraph is currently unsupported. This will be supported in the future.
