XML Schema - element with text and attributes

For some reason I always forget how to define an element that contains only text but also has attributes. Perhaps it's because it's so verbose, or so non-intuitive for something so simple, who knows. Either way it's something that needs to be committed to memory...

So the element:

<foo bar="bar" baz="baz"/>

is described using:

<xs:complexType name="foo">
    <xs:simpleContent>
        <xs:extension base="xs:string">
            <xs:attribute name="bar" type="xs:string"/>
            <xs:attribute name="baz" type="xs:string"/>
        </xs:extension>
    </xs:simpleContent>                
</xs:complexType>

nice!
