When upgrading pre-servlet 2.4 webapps to a servlet 2.4 level container, one can usually replace a large amount of <c:out> tags with the simpler and cleaner ${..} syntax. The conversion is not 100% safe, since (IIRC) the <c:out> tag does escaping by default, while ${..} does not. Still it would be very valuable to have at least an intention action to perform this transformation. The description should of course mention the slightly different semantics referred to above.
