I wanted to make sure I understood AndyS's semantics here, in
particular, how they interact with sameTerm, so I wrote up a separate
manifest:
  http://www.w3.org/2001/sw/DataAccess/tests/data/OpenWorld/sameTerm-manifest.ttl

The only interesting one is the last one,
sameTerm-not-eq-StringSimpleLiteralCmp, which tests
  !sameTerm('xyz', 'xyz'^^xsd:string) and 'xyz'='xyz'^^xsd:string
and discovers that they are equivalent but not the
same term (as they are without StringSimpleLiteralCmp).
