I think one can only use <attribute ... use="prohibited"/> in a
and <anyAttribute> in the base definition of the complexType or in an
if you do not specify namespace.
Therefore, if the <anyAttribute> occurs later in the type deriviation
even "foo" will be legal.  If the <attribute use="prohibited"> occurs later
in the
type derivation chain, foo will not be legal.  I do not think you can
both the <anyAttribute> without namespace and the <attribute .. use
="prohibited"> at the same
level of the type derivation hierarchy.

However, the question still remains, what if this is a restriction, the
base complexType had anyAttribute with no namespace, and this type is
<complexType name="derivedType">
   <restriction base="baseType">
    <attribute name="foo" use="prohibited"/>
    <anyAttribute namespace="##targetNamespace"/>
