Additionally generating a warning if prohibition is used with
extensions would be good. The following does not produce neither
a warning nor an error with Xerces-J and XSV:

<xsd:complexType name="base">
	<xsd:attribute name="boo" use="optional"/>
</xsd:complexType>

<xsd:complexType name="type-1">
	<xsd:complexContent>
		<xsd:extension base="f:base">				
			<xsd:attribute name="boo" use="prohibited"/>
		</xsd:extension>
	</xsd:complexContent>
</xsd:complexType>
