Group redefinition isn't supported in XSV yet, sorry.

In any case, your attempt isn't valid, you need to redefine the group
_in terms of itself_, i.e.

 <xs:redefine schemaLocation="schema1.xsd">
  <xs:group name="testGroup">
   <xs:choice>
    <xs:groupref="testGroup"/>
    <xs:element name="b"/>
   </xs:choice>
  </xs:group>
 </xs:redefine>

*But*, having said that, don't use redefine at all, use substitution
groups.  That's the easy way to allow _post-hoc_ additions to choices.
