 * A proxy group is used to proxify all validation and filtering to a given element.
 * A proxy acts as a group but does not have a concrete name.
 * Thus it does not modify the namespace of descendant elements
 *
 * A concrete usage case is as a radio group: it will gather radios in one radio group
 * that will take validators and filters. Then validation messages will be shown in the proxy and not in the radio
 * and it wont modify the name of other elements (for instance you want to have radio and input text in the same group)
