A Subject Relation is a URI. It is comprised of a ContextId URI combined with an optional identifier string called a SubjectId which if present is preceded by a forward slah, that uniquely identifies a Digital Subject within the Context identified by the ContextId. The SubjectId may only be omitted when the Context identified by the ContextId contains exactly one Digital Subject.
