+/**
+ * TChoiceFormat class.
+ * 
+ * This component performs message/string choice translation. The translation
+ * source is set in the TGlobalization handler. The following example
+ * demonstrated a simple 2 choice message translation.
+ * <code>
+ * <com:TChoiceFormat Value="1"/>[1] One Apple. |[2] Two Apples</com:TChoiceFormat>
+ * </code>
+ *
+ * The Choice has <b>Value</b> "1" (one), thus the translated string
+ * is "One Apple". If the <b>Value</b> was "2", then it will show
+ * "Two Apples".
+ *
+ * The message/string choices are separated by the pipe "|" followed
+ * by a set notation of the form
+ *  # <tt>[1,2]</tt> -- accepts values between 1 and 2, inclusive.
+ *  # <tt>(1,2)</tt> -- accepts values between 1 and 2, excluding 1 and 2.
+ *  # <tt>{1,2,3,4}</tt> -- only values defined in the set are accepted.
+ *  # <tt>[-Inf,0)</tt> -- accepts value greater or equal to negative infinity 
+ *                       and strictly less than 0
+ * Any non-empty combinations of the delimiters of square and round brackets
+ * are acceptable.
+ * 
+ * The string choosen for display depends on the <b>Value</b> property. 
+ * The <b>Value</b> is evaluated for each set until the Value is found
+ * to belong to a particular set.
+ *
+ * Properties
+ * - <b>Value</b>, float, 
+ *   <br>Gets or sets the Value that determines which string choice to display.
