I understand. In particular your experiences are quite persuasive.

This makes things clearner.  I'll try to modify the code as soon as you
implement the methods mentioned above.

After the patches are officially adopted, I'll try to reimplement the XIM
support with the NSInput/NSTextInput paradigm.

After sending my previous email, I spent several hours to read Apple's
document that you told me in one of your previous email. Now I understand
the implication of your suggestion, which I found theoretically, logically
sound.  I feel, however, that I need to examine all the implementation
of the relevant classes to make sure if the XIM support can be built on
the basis of the classes.  Also, as you suggested, it may be necessary
for me to write some extra code beyond the XIM support.

I would be happy if you could also cooperate with me in the "proper"
implementaion in near future.
