What's this mean in web.xml?

Question

As part of assigning portal desktops, we've altered the web.xml file to add an additional portal alias - the portal system was, at that time, a 6.40 system.  The additional portal alias worked great.  However, I was comparing web.xml files from the deployed portal application (now at 7.0 SP10) and the web.xml that we currently use, and I found these new bits in the new web.xml:
<init-param>
  <param-name>
    wsrp_producer_service
  </param-name>
  <param-value>
    ProducerImpl
  </param-value>
</init-param>
and
<servlet-mapping>
  <servlet-name>gateway</servlet-name>
  <url-pattern>/wsrp/producer/resource/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
  <servlet-name>gateway</servlet-name>
  <url-pattern>/wsrp/consumer/resource/*</url-pattern>
</servlet-mapping>
I can only assume that these entries have something to do with the Federated portal (and perhaps the producer part) since WSRP is the protocol used to access remote portlets (iViews).
Can someone verify?

Hi Ken,
These entries are dedicated to WSRP usage either as consumer or as producer and have no role in the FPN (remote role assignment and remote deltalinks).
Thes entries map the urls dedicated for fetching of static resources from the remote system.
