In section 3.4.6, constraint "Derivation Valid (Restriction, Complex)", there
is note:

"Note: Attempts to derive complex type definitions whose {content type} is
element-only by restricting a {base type definition} whose {content type} is
empty are not ruled out by this clause."

Why isn't this ruled out? The derived type allows whitespaces as the content,
but the base type doesn't allow it.
