Mikael, Jon, Tom, > Thus, an argument such as "if the property value is a *plain* > literal we > should use xml:lang" might possibly be more correct! Unfortunately, identifying plain text from encoded text is not so simple for an application. However, since the consensus seems to be against applying xml:lang to all literals I will ask Mitsuharu to remove them from the literals that are not obviously natural language. The registry will have to work around the problem. Regards, Harry
