Thanks. It seems that it does not violate Style Guide.
The only problem is that we use Xt to install accelerators but on
Label widget Initialize method OSF puts this code:


    ... some stuff deleted ...

    /* Accelerators are currently only supported in menus */

    if ((lw->label._acc_text != NULL) &&
        ((lw->label.menu_type == XmMENU_POPUP) ||
         (lw->label.menu_type == XmMENU_PULLDOWN)))
     {
                ... stuff that set the accelerator text ...
    }
    else
        lw->label._acc_text = NULL;

     ... same stuff for accelerator ...

     ... other stuff deleted ...


   if ((XtClass(lw) == xmLabelWidgetClass) &&
       ((lw->label.menu_type == XmMENU_POPUP) ||
        (lw->label.menu_type == XmMENU_PULLDOWN) ||
        (lw->label.menu_type == XmMENU_OPTION)))
   {
      lw->primitive.traversal_on = FALSE;
      lw->primitive.highlight_on_enter = FALSE;

      XtOverrideTranslations(lw,
        ((XmLabelClassRec *)XtClass(lw))->label_class.translations);
   }

 that makes a little hard to make accelerators working.

 I suppose that FORCING to NULL string is a constrain to respect
 the Style guide.

 If you want to permit to install acc "not in a menu" you must remove
 the 'else' part.
