Fix errors with inheritance to and from mtr nodes. (mtr should not inherit column or row align from mtable, and mtd should not inherit from mtr at all. The spec is a bit misleading about this, in that these attributes are not actually inherited per se, but their values are taken from the corresponding position within the parent mtable (or mtr) attribute. So no actual inheritance is needed from mtables or mtrs.)
