For example, if one of a node's SIDP values indicates that the node's subject is a name, and another SIDP value indicates that the node's subject is a set of subjects, the definition of the TM Application can require such a node to be regarded as exhibiting an invalid combination of SIDP values. By stating such a constraint, the TM Application's definition can reflect its designers' conviction that there can never be a single subject that is both a name and a set.
