/**
 * UISelectItems is a component that may be nested
 * inside a {@link UISelectMany} or {@link UISelectOne} component, and
 * causes the addition of one or more {@link SelectItem} instances to the
 * list of available options in the parent component.  The
 * value of this component (set either directly, or acquired
 * indirectly a {@link javax.el.ValueExpression}, can be of any
 * of the following types:
 * 
 * Single instance of {@link SelectItem} - This instance is
 *     added to the set of available options for the parent tag.
 * Array of {@link SelectItem} - This set of instances is
 *     added to the set of available options for the parent component,
 *     in ascending subscript order.
 * Collection of {@link SelectItem} - This set of instances is
 *     added to the set of available options for the parent component,
 *     in the order provided by an iterator over them.
 * Map - The keys of this object (once converted to
 *     Strings) are assumed to be labels, and the values of this object
 *     (once converted to Strings)
 *     are assumed to be values, of {@link SelectItem} instances that will
 *     be constructed dynamically and added to the set of available options
 *     for the parent component, in the order provided by an iterator over
 *     the keys.
