on values

There is a lot of wording like
  Each value of sh:targetNode is either an IRI or a literal.
in Shapes Constraint Language (SHACL) W3C Editor's Draft 02 December 2016,
where the relevant definition of value in the document appears to be
  The values of a property p for a node n in an RDF graph are the objects of
  the triples in the graph that have n as subject and p as predicate.

This statement is not universally true, such as in the RDF graph
  _:a sh:targetNode _:b .

Presumably the statement is meant to be interpreted in some context, but
there is no context given in the neighbourhood of the statement.
