ZVON comment: Element "foo" must have just one "bar" element, nothing else.

Correct schema

<element name="foo" xmlns:html="http://www.w3.org/TR/REC-html40" xmlns="http://relaxng.org/ns/structure/1.0" >
     <choice>
          <element name="bar">
               <empty/>
          </element>
     </choice>
</element>


Valid document:
<foo>
     <bar/>
</foo>

Invalid document:
<foo/>
