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.
