Forcing a certain document element

I would like to force a single document element to be valid in my
schema, however I have designed my sechma so it looks like (for
illustration purposes only):

<schema>
  <element name="documentElement">
    <complexType>
      <element ref="someRefElement" minOccurs="0"
maxOccurs="unbounded"/>
    </complexType>
  </element>

  <element name="someRefElement">
    <complexType>
      <attribute name="foo" use="required"/>
      <attribute name="bar" use="required"/>
    </complexType>
  </element>
</schema>

And I would like this XML document to validate:
 
<documentElement>
  <someRefElement foo="1" bar="2"/>
</documentElement>

But not have this validate:

<someRefElement foo="1" bar="2" />

(where "someRefElement" is the document element).

How can I use XSDL to enforce this?

Ian.
