I would prefer to see standardization of particular datatypes
be done at the API level, not the language level. RDF should
be datatype agnostic. The fact that e.g XML Schema defines
a standardized set of datatypes which can serve as a basis
for interoperability is how it should work, and that does not
e.g. prohibit other standards such as UAProf, to take a real
world example, from defining their own datatypes which are
not all derivable from XML Schema datatypes.
