Message to OWL comments on common datatypes

[Is this indeed the sentiment of the RIF WG? - Chris]

In our discussions on using RIF Core to represent the rules in the OWL-RL 
profile, we could not perceive value for our user base in adopting owl:rational 
but note that is already At Risk in the current OWL2 drafts. We also did not see 
value in requiring support for the string subtypes xsd:normalizedString, 
xsd:token, xsd:Name, xsd:NCName and xsd:NMTOKEN, though these are still under 
discussion.

This comment began within the context of the OWL-RL profile, however we would 
like to work towards a common set of datatypes for the semantic web.
