Creates a marker for the resource identifier property.
Tags the enclosing property as mapping to JSON-LD @id. At most one id marker is allowed per resource shape,
counted after inheritance merging: markers sharing a property name collapse into a single entry, so a marker
reaching the shape through several parents or redeclared by the shape counts once, while two id markers under
distinct property names are rejected. The resulting property has implicit 0..1 cardinality and accepts a single
absolute IRI value.
