> I'd like to be able to create reusable {{RedeliveryPolicy}}'s in Spring and refer to
them in Camel's Spring DSL.  This is to achieve two goals:
>  * I can use the Spring {{PropertyPlaceholderConfigurer}} to enable us to tune timeouts
and redelivery in production - we cannot do that with Camel's Spring DSL;
>  * I can have several routes sharing the same {{RedeliveryPolicy}} (but possibly with
different exceptions).  
> There doesn't seem to be a way to share {{RedeliveyPolicy}}'s between {{onException}}
elements, meaning it needs to be duplicated (at least not that I could find in the docco)
> For example, I'd like to do something like this:
> {code}
>     <bean id="redeliveryPolicy" class="org.apache.camel.processor.RedeliveryPolicy">
>         <property name="..." value=${property.placeholder}/>
>     </bean>
>     <camelContext>
>         <route>
>             <from uri="somewhere"/>
>             <onException>
>                 <exception>ExceptionA</exception>
>                 <redeliveryPolicy ref="redeliveryPolicy"/>
>                 <to uri="deadLetter"/>
>             </onException>
>             <to uri="unreliableEndpoint"/>
>         </route>
>         <route>
>             <from uri="xyz"/>
>             <onException>
>                 <exception>ExceptionA</exception>
>                 <redeliveryPolicy ref="differentRedeliveryPolicy"/>
>                 <to uri="differentDeadLetter"/>
>             </onException>
>             <to uri="unreliableEndpoint"/>
>         </route>
>         <route>
>             <from uri="somewhereElse"/>
>             <onException>
>                 <exception>ExceptionB</exception>
>                 <redeliveryPolicy ref="redeliveryPolicy"/>
>                 <to uri="deadLetter"/>
>             </onException>
