So Toms' observation is correct (since he also used myfaces) | | If I do not have doctypes in my pages, my eclipse plugin (exadel) cannot validate the pages, so I definately want the docstypes in. Well if the difference is between being broken for everyone using the RI, and not having eclipse be able to validate the XML, I'd rather break eclipse.
