required

I'm trying to create xsd for an element like this:

<ElementType attr1="a" attr2 ="b">mandatory_string</ElementType>

and I want to make the mandatory_string required. What should I add to this xsd:

<xs:complexType name="ElementType">
 <xs:simpleContent>
  <xs:extension base="xs:string">
   <xs:attribute name="attr1" type="StringLength1to2" use="required"/>
   <xs:attribute name="attr2" type="StringLength1to2" use="required"/>
  </xs:extension>
 </xs:simpleContent>
</xs:complexType>

Currently is optional. What's missing?
