  ---------------------------------------------------------
  
  You can configure one or more route policies (separated by comma), such as:
  
  [source,java]
  ----
  from("seda:foo").routePolicy(myPolicy, myOtherPolicy).to("mock:result");
  ----
  
  And in XML:
  
  [source,xml]
  ---------------------------------------------------------
  <route routePolicyRef="myPolicy,myOtherPolicy">
      <from uri="seda:foo"/>
      <to uri="mock:result"/>
  </route>
  ---------------------------------------------------------
  
  == Using RoutePolicyFactory
  
  If you want to use a route policy for every route, you can use
  a `org.apache.camel.spi.RoutePolicyFactory` as a factory for creating
  a `RoutePolicy` instance for each route. This can be used when you
  want to use the same kind of route policy for all or some routes.
  
  With the factory you only need to configure this once, and every route created will
  have the policy assigned.
  
  There is API on `CamelContext` to add a factory, as shown below
  
  [source,java]
  ----------------------------------------------------------
  context.addRoutePolicyFactory(new MyRoutePolicyFactory());
  ----------------------------------------------------------
  
  And from XML DSL you just define a `<bean>` with the factory, and Camel wil automatic detect this factory:
  
  [source,xml]
  ----------------------------------------------------------------------
  <bean id="myRoutePolicyFactory" class="com.foo.MyRoutePolicyFactory"/>
  ----------------------------------------------------------------------
  
  You can have as many route policy factories as you want, so if you have two factories,
  you can just add them both as shown:
  
  [source,java]
  ----------------------------------------------------------
  context.addRoutePolicyFactory(new MyRoutePolicyFactory());
  context.addRoutePolicyFactory(new MyOtherRoutePolicyFactory());
  ----------------------------------------------------------
  
  And in XML:
  
  [source,xml]
  ----------------------------------------------------------------------
  <bean id="myRoutePolicyFactory" class="com.foo.MyRoutePolicyFactory"/>
  <bean id="myOtherRoutePolicyFactory" class="com.foo.MyOtherRoutePolicyFactory"/>
  ----------------------------------------------------------------------
