I think the name attribute is indeed prohibited, and I think the place where
this is defined is in the schema for schemas (which is normative). The
simpleType element has different types depending where it appears.
Specifically, in the schema for datatypes we find:
<xs:complexType name="localSimpleType">
<xs:complexContent>
<xs:restriction base="xs:simpleType">
<xs:sequence>
<xs:element ref="xs:annotation" minOccurs="0"/>
<xs:group ref="xs:simpleDerivation"/>
</xs:sequence>
<xs:attribute name="name" use="prohibited">
