    Well, he can also change the xrm_name .....

    But first of all, WHY anybody wants to do that ?  May be there
    is some (better or easier) way to accomplish THAT than changing
    the instance *name*.

    The widget *name* (or better xrm_name as objects do NOT store the
    name string) is used at widget creation time to retrieve resources
    from Xrm database. Then it is used by XtNameToWidget. 
    It may be used in some other instances as well ... for example,
    Label widgets tend to use this name as a default string.
    I think that changing the name goes into the same bag as reparenting
    widgets. Technically, it can be done, but it feels too close to
    a kluge to justify doing it.
