The problem is not that the datatypes don't meet your conditions above, the
problem occurs when two datatypes share some data values, but disagree on
how to to the lexical-to-value mapping. If the typing comes from RDF(S),
then it may be the case that a literal gets these two datatypes. Then the
value for that literal is ambiguous.
