Switch

• The <switch> construct allows you to select exactly one branch of activity from a set of choices.

<switch standard-attributes>
  standard-elements
  <case condition="bool-expr">+
    activity
  </case>
  <otherwise>?
    activity
  </otherwise>
</switch>

<!-- for example -->

<switch xmlns:inventory="http://supply-chain.org/inventory" 
        xmlns:FLT="http://example.com/faults">
  <case condition= "bpws:getVariableProperty(stockResult,level) > 100">
    <flow>
       <!-- perform fulfillment work -->
    </flow>
  </case>
  <case condition="bpws:getVariableProperty(stockResult,level) >= 0">
    <throw faultName="FLT:OutOfStock" 
           variable="RestockEstimate"/>
  </case>
  <otherwise>
    <throw faultName="FLT:ItemDiscontinued"/>
  </otherwise>
</switch>
