471	JVET-O0050 - Context derivation for mode_constraint_flag	bheng		"For the purposes of mode constraints (JVET-O0050), IBC is treated as intra prediction. Specifically, CUs with MODE_TYPE_INTRA can use either MODE_INTRA or MODE_IBC prediction.

With that in mind, for context derivation why is only MODE_INTRA considered and MODE_IBC is treated as inter?

Specifically, the following row from Table 9-18.

mode_constraint_flag	
CuPredMode[ xNbL ][ yNbL ] = = MODE_INTRA	
CuPredMode[ xNbA ][ yNbA ] = = MODE_INTRA


Should these conditions be (MODE_INTRA | | MODE_IBC) instead?
