Environment:  Hardware- Sun 3/50, OS-Sun 3.4, X- X.V11R2, Fixes- none applied
Problem:
    I have two windows, 'A' and 'B'.  'A' calls 
        XSetSelectionOwner(..., XA_PRIMARY, 'A', CurrentTime);
	
    Any calls to XConvertSelection send the proper SelectionRequest events
    to 'A' and the selected data can be passed properly via SelectionNotify.
    
    At some later time, 'B' calls
        XSetSelectionOwner(..., XA_PRIMARY, 'B', CurrentTime);
	
    Again, calls to XConvertSelection can retrieve the proper data from 'B'.
    However, window 'A' never received a SelectionClear event.  This used
    to work under X.V11R1.  I need to know if this is 1) a problem with
    X.V11R2,  2) a problem with the Sun specific code,  or 3) a problem with
    my understanding of the documentation.

    Please reply if any of you can tell me what is going on.  I hesitate to
    report this as a bug considering how obvious it is.  I suspect a flaw
    in my understanding. 
    The documentation on fixes 1 - 11 does not mention SelectionClear, and I 
    do not apply patches unless they address a specific problem I am having.
    
                                        Thanks in advance.
