ORDER BY in View's subquery

The student guide for Introduction to Oracle9i: SQL mentioned that "the subquery that defines the view cannot contain an ORDER BY clause" (chap 11-8). But I tested this with 9iR2 and the ORDER BY is allowed?! Is this just a difference between 9iR1 and 9iR2? Or is there something I am missing and a view's query really cannot have an ORDER BY ?
