The proof of containment is similar to Theorem 2 except that the the tables of rules in the second phase of the 2D grammars TRMG [12] and TCFMG [12] of the corresponding TRML and TCFML are taken as the row tables of the E2DCFPG.The proper containment follows from the same example 1 as even in a TRMG or a TCFMG the two phases of derivation are independent.
