I think the model group itself is fine.  What the error is saying is you 
can't have:

 <xs:element name="configure">
   <xs:complexType>
    <xs:sequence>
      <xs:all ...></xs:all>
    </xs:sequence>
   </xs:complexType>
 </xs:element>

(i.e. XML schema does not allow xs:all to be a particle.)

Instead you can do:

 <xs:element name="configure">
   <xs:complexType>
      <xs:group ref="group_1" minOccurs="0" maxOccurs="1"/>
   </xs:complexType>
 </xs:element>

HTH,

Pete.
