Thanks Ross for this perfect explanation how contracts work with a given
presentation model (pm) and in general. A presentation model is a given
data model that has to been transformed.

Now I just used the features that always have been part of views to not
use a default pm anymore. That means that all data (pm) needed by
contracts should be requested by the view and pass it over to the
contract.

The most famous content-feeder contract is the example of how we will do
it in the core (requesting the pm instead of taking it for granted):
<forrest:contract name="content-feeder">
    <forrest:properties contract="content-feeder">
      <forrest:property name="content-feeder"
nugget="get.nugget.feeder">
        <url>/feeds/somefeed.xml</url>
      </forrest:property>
    </forrest:properties>
</forrest:contract>

Ross found a better way how to enhance this way and is preparing a
proposal for making views cocoon-block enable. I am looking forward to
it. :)

...and yes views are a moving target like os in general, which is the
good thing about it. Things get enhanced through growing. ;-)
