    00029 * "Between" condition.  We use the standard ISO/IEC 9075:1992 semantic,
    00030 * according to which "X between Y and Z" is equivalent to "X >= Y && X <= Z".
    00031 * In a case when either result of a method invocation or a value to compare
    00032 * are equal to null, the <tt>evaluate</tt> test yields <tt>false</tt>.
    00033 * This approach is equivalent to the way the NULL values are handled by SQL.
