Can a DDL rollback apply to the outer transaction?

It is unclear whether the rollback applies to the wrapped DDL statements only, as-if the create schema started a save-point, or the outer transaction with possibly some prior DML statement. You still cannot avoid the commit after the last wrapped DDL statement complete successfully though.

In addition some statements, like an alter table statement, may fail if another session has an open transaction on the object being modified or one of its dependencies.
