Error in example fragment in 6.2.3

Hi

The example in 6.2.3 Interaction Syntax has two variable declarations of the same name, which is no longer permitted:

      <variable name="badPurchaseOrderAck"   
                informationType="tns:badPOAckType" roleTypes="tns:Consumer"/>
      <variable name="badPurchaseOrderAck"   
                informationType="tns:badPOAckType" roleTypes="tns:Retailer"
                silent="true" />
As it says in section 5.2:" The attribute name is used to specify a distinct name for each variable declared within the variableDefinitions element. "RegardsGary
