Transparency Enabling Properties, the semantic extension proposed by the CG to lift the syntactic constraints on quoted triples and implement referentially transparent quoted triples, see Sections 6.4.5 'Selective referential transparency' [0] and 7.2 'Extended vocabulary' [1] of the RDF-star CG report. 

Note that the semantic extension has to be invoked per property per graph. Neither can a property be declared to always make quoted triples referentially transparent nor can one property be used in the same graph on referentially opaque quoted triples AND on referentially transparent quoted triples.
