{
 *  kEventClassAccessibility / kEventAccessiblePerformNamedAction
 *  
 *  Summary:

 *  
 *  Discussion:
 *    The kEventParamAccessibleActionName parameter will contain an
 *    attribute name in the form of a CFStringRef. If you support the
 *    named action, perform the action. There are times, however, when
 *    performing an action causes an accessible object to call a
 *    routine which may not return immediately, such as StandardAlert
 *    or PopUpMenuSelect. You should only call such routines when you
 *    receive an action request that was queued; if you call such a
 *    routine when processing an event that was directly dispatched,
 *    you will probably cause the assistive app to receive a timeout
 *    error. On Mac OS X 10.3 and later, the
 *    kEventParamAccessibilityEventQueued parameter will indicate
 *    whether the event was queued. If so, process the request
 *    normally. If not, you can request that the event be posted to the
 *    queue and sent to you later by returning
 *    eventDeferAccessibilityEventErr from your handler. On Mac OS X
 *    10.2, the parameter will not exist, the event will always be
 *    directly dispatched, and there is no way to request that it be
 *    posted to the queue; in this case, you should perform the action
 *    even if it will cause the assistive app to receive a timeout
 *    error.

{
 *  AXUIElementCreateWithHIObjectAndIdentifier()
 *  
 *  Discussion:
 *    This routine creates an AXUIElementRef to represent an accessible
 *    object for a Carbon application. A Carbon accessible object is
 *    comprised of an HIObjectRef and a 64-bit identifier. The
 *    resulting AXUIElementRef is a CFTypeRef, and must be managed as
 *    such. You can create a new AXUIElementRef every time you need
 *    one. Even though the actual hex values of two AXUIElementRefs
 *    might be different, they may represent the same accessible
 *    object; because AXUIElementRefs are Core Foundation objects, you
 *    can use CFEqual to compare them.
 *  
 *  Mac OS X threading:
 *    Not thread safe
 *  
 *  Parameters:
 *    
 *    inHIObject:
 *      The HIObjectRef of the accessible object.
 *    
 *    inIdentifier:
 *      The 64-bit identifier of the accessible object.
 *  
 *  Result:
 *    An AXUIElementRef that represents the Carbon accessible object
 *    identified by the given HIObjectRef and 64-bit identifier. This
 *    follows CoreFoundation semantics in that it will return NULL for

 *  
 *  Summary:

 *  
 *  Discussion:
 *    This routine is useful if you are implementing an accessible
 *    object that has a standard role or role-subrole pair and you want
 *    to make sure your object provides the same role description
 *    string that the equivalent system-supplied object provides. In
 *    other words, if you are implementing an accessible object of role
 *    kAXButtonRole, you can use this routine to make sure it provides
 *    the same role description that the standard push button provides.
 *    
 *    This routine can provide role description strings for all roles
 *    and role-subrole pairs that are used in the standard/system
 *    accessible objects on Mac OS X 10.4 and later. Once this routine
 *    is able to provide a role description string for a role or

 *  
 *  Parameters:
 *    
 *    inRole:
 *      The role CFStringRef for your accessible object. Callers
 *      typically pass one of the kAXFooRole constant strings from
 *      within the HIServices framework.

 *      object does not have a subrole.
 *  
 *  Result:
 *    A CFStringRef with the standard role description for the role or

{
 *  HIObjectSetAuxiliaryAccessibilityAttribute()
 *  
 *  Summary:
 *    Associates an additional accessibility attribute with a UIElement
 *    that is used to represent a given HIObject or a part thereof.
 *  
 *  Discussion:
 *    This routine lets your application provide the name of and data
 *    for an accessibility attribute that you want to add to the
 *    UIElement used to represent a given HIObject-identifier pair.
 *    Normally, accessibility attributes can only be supplied
 *    dynamically via Carbon Events, but this routine allows you to
 *    supply them statically. 
 *    
 *    When an accessibility attribute Carbon Event is handled by the
 *    HIObject with a given identifier, the toolbox automatically
 *    supplies the names and/or values of any auxiliary attributes
 *    associated with that HIObject- identifier pair. 
 *    
 *    This routine is particularly useful for supplying values for the
 *    kAXDescriptionAttribute, kAXTitleUIElementAttribute,
 *    kAXServesAsTitleUIElementAttribute, kAXLinkedUIElementsAttribute
 *    and other attributes whose value is specific to the layout and
 *    usage of your application. 
 *    
 *    This routine only allows you to associate attributes whose values
 *    never change. If you need to supply attributes whose values are
 *    determined dynamically or whose values are settable, you must
 *    install the normal accessibility Carbon Event handlers. 
 *    
 *    The auxiliary attribute store is consulted during the HIObject's
 *    default handling of the accessibility attribute Carbon Events.
 *    This means that any programmatic handling of a given
 *    accessibility attribute will have a chance to override or block
 *    the consultation of the store. The general rule is that if the
 *    toolbox or a Carbon Event handler can provide the attribute value
 *    some other way, the store will not be consulted.
 *  
 *  Mac OS X threading:
 *    Not thread safe
 *  
 *  Parameters:
 *    
 *    inHIObject:
 *      The HIObjectRef part of the object-identifier pair to which the
 *      attribute data is associated.
 *    
 *    inIdentifier:
 *      The 64-bit identifier part of the object-identifier pair to
 *      which the attribute data is associated. When you want to
 *      associate the attribute data to the HIObject as a whole -- such
 *      as when you want to give a description attribute to a push
 *      button -- you should pass zero in this parameter.
 *    
 *    inAttributeName:
 *      A CFStringRef of the name of the attribute you wish to
 *      associate with the object-identifier pair. This string will be
 *      retained before adding it to the auxiliary attribute store.
 *    
 *    inAttributeData:
 *      A CFTypeRef with the data to be supplied as the attribute's
 *      value. This data will be retained before adding it to the
 *      auxiliary attribute store; you may release inAttributeData
 *      after you have called this routine. The inAttributeData
 *      parameter may also be NULL, which indicates that the named
 *      auxiliary attribute should no longer be associated with the
 *      object-identifier pair; any named attribute data previously
 *      associated with the object-identifier pair will be released.
 *  
 *  Result:
 *    An OSStatus result code. The function will return noErr if it was
 *    able to associate the attribute data with the HIObjectRef. If the
 *    HIObjectRef is invalid, paramErr will be returned. Other results
 *    may be returned in other situations.

{
 *  HIObjectOverrideAccessibilityContainment()
 *  
 *  Summary:
 *    Allows you to override the AXUIElementRefs that an HIObject would
 *    normally supply as the values of its AXParent, AXWindow, and
 *    AXTopLevelUIElement attributes.
 *  
 *  Discussion:
 *    This routine allows you to change the parent that an HIObject
 *    would normally supply in the accessibility hierarchy. For
 *    instance, a popup control could call this routine on its menu so
 *    that the menu returned the popup control as the menu's parent;
 *    normally the menu would return the application as its parent.
 *    Optionally, this routine also allows you to change the window and
 *    top-level element that an HIObject would normally supply. 
 *     
 *    If the input HIObject is a standard toolbox construct like an
 *    HIView or a Menu, the input HIObject will not be added as an
 *    accessibility child of its normal parent. In all other cases, it
 *    is the client's responsibility to ensure that the input HIObject
 *    is not added as an accessibility child of its normal parent. 
 *     
 *    If the desired AXUIElementRef parent represents an HIView, a
 *    Menu, or a Window, the input HIObject will be automatically added
 *    as an accessibility child of the specified parent. In all other
 *    cases, it is the client's responsibility to manually add the
 *    input HIObject as a child of the specified parent. To represent
 *    an HIView, a Menu, or a Window, an AXUIElementRef must contain
 *    the appropriate HIObjectRef as well as an identifier value of
 *    zero. 
 *    
 *    Similar rules don't have to apply for the handling of the window
 *    and top-level element attributes because those attributes don't
 *    represent two-way relationships. 
 *    
 *    A containment override is not necessarily supported by every type
 *    of HIObject. Currently, it is supported by HIViews, Menus, and
 *    Windows.
 *  
 *  Mac OS X threading:
 *    Not thread safe
 *  
 *  Parameters:
 *    
 *    inHIObject:
 *      The HIObjectRef whose parent attribute you want to override.
 *    
 *    inDesiredParent:
 *      The AXUIElementRef that you wish the HIObject to return as the
 *      value of its AXParent attribute. This routine makes a copy of
 *      the AXUIElementRef; you must release inDesiredParent after you
 *      have called this routine. Passing NULL indicates that you want
 *      the HIObject to revert to its normal, un-overridden behavior.
 *    
 *    inDesiredWindow:
 *      The AXUIElementRef that you wish the HIObject to return as the
 *      value of its AXWindow attribute. This routine makes a copy of
 *      the AXUIElementRef; you must release inDesiredWindow after you
 *      have called this routine. Passing NULL indicates that you want
 *      the HIObject to report its normal window, if any.
 *    
 *    inDesiredTopLevelUIElement:
 *      The AXUIElementRef that you wish the HIObject to return as the
 *      value of its AXTopLevelUIElement attribute. This routine makes
 *      a copy of the AXUIElementRef; you must release
 *      inDesiredTopLevelUIElement after you have called this routine.
 *      Passing NULL indicates that you want the HIObject to report its
 *      normal top-level element, if any.
