Not saying that it's the answer, but isn't that very close to the
system-config-* tools in Fedora ?

Just a wild thought: you could simulate that with Augeas with doing the
following:
     1. pass AUG_SAVE_NEWFILE to aug_init, so that aug_save will write
        new stuff into files with .augnew extension
     2. when users create a new entry in Config::Model, create a
        'template' entry behind the scenes that you know is
        syntactically correct, and as users fill in fields, modify the
        template entry accordingly (those template entries would have to
        be written manually for each config file)
     3. every time you want to validate, call aug_save
     4. when the user hits 'save' in the UI, call aug_save and move
        the .augnew file over the 'proper' file
