+/**
+ * TChoiceFormat class.
+ *
+ * This component performs message/string choice translation. The translation
+ * source is set in the TGlobalization module. The following example
+ * demonstrates 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> is "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.
+ * Since version 3.1.2 the following set notation is also possible.
+ *
+ *  # <tt>{n: n % 10 > 1 && n % 10 < 5}</tt> --  matches numbers like 2, 3, 4, 22, 23, 24
+ *
+ * Where set is defined by the expression after <tt>n:</tt>. In particular, the expression
+ * accepts the following mathematical/logical operators to form a set of logical conditions
+ * on the value given by <tt>n</tt>:
+ *   # <tt>&lt;</tt> -- less than.
+ *   # <tt>&lt;=</tt> -- less than equals.
+ *   # <tt>&gt;</tt> -- greater than.
+ *   # <tt>&gt=</tt> -- greater than equals.
+ *   # <tt>==</tt> -- of equal value.
+ *   # <tt>%</tt> -- modulo, e.g., 1 % 10 equals 1, 11 % 10 equals 1.
+ *   # <tt>-</tt> -- minus, negative.
+ *   # <tt>+</tt> -- addition.
+ *   # <tt>&amp;</tt> -- conditional AND.
+ *   # <tt>&amp;&amp;</tt> -- condition AND with short circuit.
+ *   # <tt>|</tt> -- conditional OR.
+ *   # <tt>||</tt> -- conditional OR with short circuit.
+ *   # <tt>!</tt> -- negation.
+ *
+ * Additional round brackets can also be used to perform grouping.
