     * The table is regular, and can be expected to stay regular in
     * future versions of WSP.  The status value is read as XYY,
     * so that X is the first digit and Y is the value of the
     * second two digits.  This is encoded as a hex value 0xAB,
     * where A == X and B == YY.
     * This limits YY to the range 0-15, so an exception is made
     * to allow larger YY values when X is 4.  X value 5 is moved up
     * to A value 6 to allow more room for YY when X is 4.
