The CGI provides to results via templates. Templates operate on the resultCacheMemberObj contents and do a layer.getFeature behind the scenes. You need only concern yourself with the presentation piece. Through templates you can:
- output, and to a certain extent format, attributes - output and format coordinates and bounding boxes - limit the number of features output - control output order of layers - define custom mime-types RFC 36 is a good place to start for the newer template support. I think I've posted a few examples to the list as well.
