How about this?

<xs:choice>
  <xs:sequence>
    <xs:element ref = "a"></xs:element>
    <xs:element ref = "b" minOccurs = "0"></xs:element>
  </xs:sequence>
  <xs:element ref = "b" minOccurs = "0"></xs:element>
</xs:choice>

Subject: defining rules for a or b or ab



Hi,
I'm trying to specify the rules a|b|ab in XMLSchema.

SCQ give an "Ambiguous content model" error stating
that the particles 'foo' from fooType and foobarType
overlap.

<choice>
  <element name = "foo" type = "fooType"/>
  <element name = "bar" type = "barType"/>
  <group ref = "foobarType"/>
</choice>

<group name="foobarType">
  <sequence>
    <element name = "foo" type= "fooType"/>
    <element name = "bar" type= "barType"/>
   </sequence>
</group>

Any suggestions?

(For some reason my first post didn't go through.
Resending..).
