...I think we say the preferable way would be to create a bugzilla "patch" entry, which for new features is just a "bug" whose description starts with [PATCH] and has the source attached, usually as a .zip file. A unified diff of the cocoon.xconf or cocoon.roles file needed to use this component impl might make it easier to apply and test, but probably not necessary.
See http://cocoon.apache.org/2.1/howto/howto-patch.html for how to prepare patches.
