Property syntax collision

[Cantor, Scott]

I ran into the first major "oh, that's a bug" with the alpha code: we have
a collision between Spring property syntax and the Velocity syntax we rely
on for things like Template attribute definitions, eg.

<resolver:AttributeDefinition xsi:type="ad:Template" id="email"
sourceAttributeID="mail">
<ad:Template>
          <![CDATA[
               ${uid}@shibboleth.net
          ]]>
        </ad:Template>
        <ad:SourceAttribute>uid</ad:SourceAttribute>
    </resolver:AttributeDefinition>

It of course crashes at startup on the undefined property. Oops.


Not sure what we can do there, for now we may just need to note it and
research later.
