There is an output module that writes to request attributes. However,
output modules are not directly accessible from the sitemap. One could
think of a generic action like the one you wrote that sets attributes
using output modules. That way this action could be used to set
e.g. session attributes and more (thinking, would it make sense to
have an response output module then, perhaps based on JXPath?)

The "TestAction.java" in src/samples/org/apache/cocoon/acting/modular/
might be useful as a blueprint for such an action, although it
focusses on testing input modules it does use output modules as well.
Just mind that output modules may require a final "commit()" before
data is actually placed in the designated store.
