  20   * TChoiceFormat class.
  21   *
  22   * This component performs message/string choice translation. The translation
  23   * source is set in the TGlobalization module. The following example
  24   * demonstrates a simple 2 choice message translation.
  25   * <code>
  26   * <com:TChoiceFormat Value="1">[1] One Apple. |[2] Two Apples</com:TChoiceFormat>
  27   * </code>
  28   *
  29   * The Choice has <b>Value</b> "1" (one), thus the translated string
  30   * is "One Apple". If the <b>Value</b> is "2", then it will show
  31   * "Two Apples".
  32   *
  33   * The message/string choices are separated by the pipe "|" followed
  34   * by a set notation of the form
  35   *  # <tt>[1,2]</tt> -- accepts values between 1 and 2, inclusive.
  36   *  # <tt>(1,2)</tt> -- accepts values between 1 and 2, excluding 1 and 2.
  37   *  # <tt>{1,2,3,4}</tt> -- only values defined in the set are accepted.
  38   *  # <tt>[-Inf,0)</tt> -- accepts value greater or equal to negative infinity
  39   *                       and strictly less than 0
  40   * Any non-empty combinations of the delimiters of square and round brackets
  41   * are acceptable.
  42   *
  43   * The string choosen for display depends on the <b>Value</b> property.
  44   * The <b>Value</b> is evaluated for each set until the Value is found
  45   * to belong to a particular set.
  46   *
  47   * Properties
  48   * - <b>Value</b>, float,
  49   *   <br>Gets or sets the Value that determines which string choice to display.
