Re: missing start elementt

Your example is correct, and should after transformation and
simplification be isomorphic with:

<grammar xmlns="http://relaxng.org/ns/structure/1.0">
  <start>
    <ref name="foo-0"/>
  </start>
  <define name="foo-0">
    <element>
      <name ns="">foo</name>
      <choice>
        <empty/>
        <ref name="foo-0"/>
      </choice>
    </element>
  </define>
</grammar>

So any tool saying otherwise is wrong.

Cheers,
David
