Hey Zach,
I think this really depends on your needs. Will you have a huge amount 
of distinct error messages, or will they be relatively generic and few 
in number?
If they are few, I would put them in the respective Settings.yaml, which 
can be accessed easily in every action controller.
If they are getting more in number, or you want to keep it generic, you 
could make e.g. an injectErrorMessageFetcher method (or any other name 
you choose) in each controller, which would let the object builder 
inject an error message fetcher of your choosing. The respective 
implementation of that fetcher would be up to you, so you could store it 
in xml, a database, or any other datasource you write the code for :)

Hmm thinking about it this does sound like a rather general problem, so 
I could see this becoming a framework component of its own. If the 
powers in charge here approve of it, I could write an interface and a 
few generic implementations.

If there is already a component like that and I managed to overlook it, 
please excuse my ignorance ;)

Hope this helps
regards,
Manuel
