(1.) The content of · Theorem 1.1; · Proposition 2.7;

of the present paper depend on the portions of the theory of [LgSch], §2, that are in error [cf. [MnLgSch], Example 0.3; [MnLgSch], Remark 1.4.1, for more details]. In particular, these errors in [LgSch], §2, affect the proof — although not the validity! — of the main theorem of the present paper [i.e., Theorem 3.4]. This result Theorem 3.4 is given a correct proof in [MnLgSch], §4 [cf. [MnLgSch], Theorem 4.8, (iv)]. Finally, we remark that, at the level of main results of papers of the author subsequent to [LgSch], the only place where the errors in the theory of [LgSch], §2, have an effect is in the present paper, as discussed above
