Yes there is. In 2002 edition it's in section 9.3.2.3(4). Generally the use of a non-rigid style grooved coupling allows enough deflection for these types of expansion joints and is acceptable to most AHJ's.
As it says in the Annex, for seismic separation joints considerably more flexibility is needed. Craig L.
