Quality Values

Alternative enclosures (ones inside the ``Enclosures'' element with ``kind'' equals to ``alternative'') use short ``floating point'' numbers to indicate their relative importance (``weight''). A weight is a normalized real number in the range 0 through 1, where 0 is the minimum value and 1 the maximum.

Composing agents must not generate more than three digits after the decimal point. User configuration of these values should also be limited in this fashion.
