ZVON comment: For each grammar element, all define elements with the same name are combined together. Here the combine attribute has value "interleave", so the elements "foo1", "foo2", and "foo3" can be interleaved.

Correct schema

<grammar xmlns:html="http://www.w3.org/TR/REC-html40" xmlns="http://relaxng.org/ns/structure/1.0" >
     <start>
          <element name="foo">
               <ref name="x"/>
          </element>
     </start>
     <define name="x" combine="interleave">
          <element name="bar1">
               <empty/>
          </element>
     </define>
     <define name="x" combine="interleave">
          <element name="bar2">
               <empty/>
          </element>
     </define>
     <define name="x">
          <element name="bar3">
               <empty/>
          </element>
     </define>
