For example, you could have gotten to the same end here
with the old method, by registering your actions with an object of your own
creation, and registering just one commit hook with the transaction, where
that one hook looked at the actions you registered with your own object and
ran them in whatever order _it_ determined was best.
Now plug and play comes into play:
Assume two packages developped by independent people
which all want to control the order of hook execution.
Do we have evidence that such applications exist? So far, the
only example I've seen is one where an application wanted a handler
to go last. As I've pointed out in a separate note, this is achievable
without the change.
I have a *package* (similar to Archetypes SQLStorage) that
wants to go after everything that might possibly change attributes
whether those changes are done by another component from me
or any package developped by someone else.
So again, you don't need ordeing, you just want to go last.
Just register an intermediate hook that registers the real
hook when it is called.
