In the set of answers the following are interpretations consistent with RDF semantics:
1) John has a telephone number, but we don't know the number.
2) John has a telephone number, which is known but hidden from view (for example, for privacy reasons).
3) I do not want John's telephone number to be externally referenced.
4) I do not want to mint a URI for John's telephone number.

They all say: there is for sure at least a number for John, but in the graph there is no reference to it.
