That's what it's supposed to illustrate. That should become clear when
I add the verbage that is supposed to go with those illustrations ;-)

No, condition 3 of the Datatyping MT in section 5 states that "25" is in
the lexical space of xsd:integer -- and therefore "25" in the context
of the datatype mapping for xsd:integer denotes the value 25. Therefore,
in the datatyping interpretation, John, Jane, and Judy all have the age 25.
