That's a bug. See

That's correct, because it's equivalent (per 4.12) to

<element xmlns="http://relaxng.org/ns/structure/1.0" name="foo">
  <mixed>
    <group>
      <element name="bar">
        <empty/>
      </element>
      <element name="bar">
        <empty/>
      </element>
      <element name="bar">
        <empty/>
      </element>
    </group>
  </mixed>
</element>
