Gotcha: 2 Preflow Tags

Proxy or Target XML file can contain multiple PreFlow tags. Though XML allows it syntactically - semantically this does not work as expected. The validation is currently missing.

 <PreFlow>
        <Request>
            <Step>
                <Name>assign_client_id</Name>
            </Step>
        </Request>
    </PreFlow>
    <PreFlow>
        <Request>
            <Step>
                <Name>assign_referrer_id</Name>
            </Step>
        </Request>
 </PreFlow>

In case of multiple PreFlow tags, only the policies in the last (textually last) PreFlow tag is executed. The policies in other PreFlow tags are silently ignored. Deployment and runtime validation are missing for this error. In the example above - only assign_referrer_id policy will be executed.
