Although a Digital Subject may have any number of identifier Identity Attributes it MUST have one identifier that uniquely identifies it within its containing Context. This identifier is called the SubjectId. Note that the containing Context also has a unique identifier, the ContextId, and that the combination of the ContextId and the SubjectId is an absolute unique identifier that is used in Higgins Relations.


Rules not defined in this ABNF are defined in the ABNF for XRI 2.0 (which includes the IRI ABNF from RFC 3987).

subjectId          = ifragment / xri-segment
