As Jos pointed out at the telecon I had "rdfs:Literal" under the 
"supported by RIF" column which is not strictly correct. It looks like I 
had been misreading it as rdf:XMLLiteral.

However, as far as I can tell the only support for rdfs:Literal needed 
for OWL2/RL can be included in the ruleset[*] without needing any 
specific RIF support and no changes to DTB. I've fixed up the rules in 
the document accordingly and added a footnote to the table to clarify.


Essentially we just need additional rules of the form:

Forall ?lt ( ?lt[rdf:type->rdfs:Literal] :- External( pred:isX(?lt)) )

For all supported datatypes X.
