Meta Element: suppress warning in certain common situations

If they have specified a default, then it doesn't matter that it's not
required.  Well most of the time it won't anyway.  Also, for fields where

is possibly OK, or at least not always worth warning about.  So keep it
relatively quiet for the time being.
