I think the idea is good, but looking at the content of all xml files would slow down deployment time, especially for large complex nested deployments. So if we did this as part of deployment it would be more efficient to do it based on file name matching. Common misspellings could be checked for using a static map. So I would still prefer extensive checking like this to be an optional deployment tool/maven task. If however someone comes up with a patch which is able to demonstrate no significant delay, we would certain reconsider. -- Jason T.
