I would suggest to have these parameters as a configuration of the
map:pipelines
section, rather than the complete sitemap.

I'm currently thinking of adding a configuration possibility to the
map:pipelines
component anyway, because of the rather ugly configuration of the
authentication
components. They are currently configured in an action but are for the
complete
sitemap.

I thought of somethink like:
<map:pipelines>
   <map:pipeline-parameters>
       <map:parameter name="skin">forrest-skin</map:parameter>
   </map:pipeline-parameters>
   <map:component-configurations>
       <authentication>
            <handlers>
                  ...
       </authentication>
   </map:component-configurations>

  <map:pipeline>
       ...
  </map:pipeline>
</map:pipelines>
