Talk:Conservative extension

In section Model-theoretic conservative extension: I believe the definition is not the intended at the moment. It should read:

if every model of T_1 can be expanded to a model of T_2 and every model of T_2 restricted to the language of T_1 is a model of T_1.

Otherwise the implication in the next sentence is wrong.
