Hi,

I'd like to use the value of a request parameter to specify a file to aggregate with my input.

For example, when the URI is

http:localhost:8888/cocoon/dir/whee.xml?sequence=zoom.xml

I'd like to have the functional equivalent of

<map:aggregate element="goforit">
  <map:part src="{1}/{request-param:sequence}"/>
  <map:part src="{1}/{2}"/>
</map:aggregate>

Except this gives me an error when the parameter is missing, where I need fallback behavior (for example, just adding nothing would do).

Thanks for any help you can offer.

Cheers,
Wendell
