That seems fine as far as it goes though it only addresses one of the four requested predicates. The original email was [1] section 3. Basically your pred:hasDatatype equates to my pred:isType (and I'm fine with your name). I'd also like a negative version (isNotType, not sure hasNotDatatype reads so well but I don't care what you call it). But it would also be very helpful to have the overloaded versions of the literal equality and inequality predicates.
