You mean: isLiteralNotOfType

I disagree. A rif:iri constant can denote an actual datatype, so you can
speak about actual datatypes when speaking about the types of literals.

In fact, it would have been best if in BLD semantic structures the IRIs
of datatypes are mapped to the corresponding datatypes, e.g., xsd:string
is mapped to the XML schema string datatype.  One could then, in DTB,
speak only about values and datatypes, which will be much more
convenient and much more elegant.
We should not have moved BLD to last call before finalizing DTB :-(
I now think we should probably redo BLD last call, after finalizing DTB.

Yes.
