Checks if two datatype literals are equal in terms of the values of their value space.

Non-RDF.Literals are tried to be coerced via RDF.Literal.coerce/1 before comparison.

Returns nil when the given arguments are not comparable as literals of this datatype.

Invalid literals are only considered equal in this relation when both have the exact same datatype and the same attributes (lexical form, language etc.).

Implementations can customize this equivalence relation via the RDF.Literal.Datatype.do_equal_value_different_datatypes?/2 and RDF.Literal.Datatype.do_equal_value_different_datatypes?/2 callbacks.
