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. [...] > Cheers, > > Patrick peter
