-/**
- * TListControlValidator class.
- *
- * TListControlValidator checks the number of selection and their values
- * for a <b>TListControl that allows multiple selection</b>.
- *
- * You can specify the minimum or maximum (or both) number of selections
- * required using the {@link setMinSelection MinSelection} and
- * {@link setMaxSelection MaxSelection} properties, respectively. In addition,
- * you can specify a comma separated list of required selected values via the
- * {@link setRequiredSelections RequiredSelections} property.
- *
- * Examples
- * - At least two selections
- * <code>
- * <com:TListBox ID="listbox" SelectionMode="Multiple">
- * <com:TListItem Text="item1" Value="value1" />
- * <com:TListItem Text="item2" Value="value2" />
- * <com:TListItem Text="item3" Value="value3" />
- * </com:TListBox>
- *
- * <com:TRequiredListValidator
- * ControlToValidate="listbox"
- * MinSelection="2"
- * ErrorMessage="Please select at least 2" />
- * </code>
- * - "value1" must be selected <b>and</b> at least 1 other
- * <code>
- * <com:TCheckBoxList ID="checkboxes">
- * <com:TListItem Text="item1" Value="value1" />
- * <com:TListItem Text="item2" Value="value2" />
- * <com:TListItem Text="item3" Value="value3" />
- * </com:TCheckBoxList>
- *
- * <com:TRequiredListValidator
- * ControlToValidate="checkboxes"
- * RequiredSelections="value1"
- * MinSelection="2"
- * ErrorMessage="Please select 'item1' and at least 1 other" />
- * </code>
