Forget about the second minOccurs:
 
<xs:choice> 
  <xs:sequence> 
    <xs:element ref = "a"></xs:element> 
    <xs:element ref = "b" minOccurs = "0"></xs:element> 
  </xs:sequence> 
  <xs:element ref = "b"></xs:element> 
</xs:choice>

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>

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..).
