If we can attach a lang tag to a literal dynamically (see #9), maybe we should be able to do the same for datatypes. This won't happen very often but it may happen that the datatype of some value is stored in a different column.
rml:datatypeMap is an IRI term map that produces a datatype IRI to be used in the current object.
rr:datatype is a constant IRI used as fallback when the IRI designated by rml:datatypeMap is null for the current row.

"integer"to a IRI likexsd:integer
