Probably the most important of my proposed tests is whether malformed literals
are correctly handled outside of embedded triples, but this test does not
appear to have been incorporated into the test suite.

This test could be transformed into an entailment test (instead of a
consistency test) as follows:



Are malformed literals handled correctly outside of embedded triples?

prefix : <http://example.com/ns#>
prefix xsd: <http://www.w3.org/2001/XMLSchema#>
:a :b "c"^^xsd:integer .

entails

prefix : <http://example.com/ns#>

:a :b :c .
