ISSUE-85 Example Policy Assertions for JMS Parameters

It is fairly simple to create WS-Policy assertions for JMS parameters.
For example, a policy assertion that says that persistent storage must 
be used may look like
    <SCA:JMS-Persistent-storage/>
This encodes the functionality in the QName of the assertion and allows 
domain-independent processing
i.e. all you need to do is recognize the QName of the assertion.

An assertion for JMS Expiration needs to be more complicated e.g.
    <SCA:JMS-Expiration>
           <duration>xsd:duration</duration>
    </SCA:JMS-Expiration>

This requires domain-specific processing since it needs to know that 
there is a child element (or attribute)
and what to do with it.
