Hi Xiaohu,
thank you for your most expedient response and kind consideration of my
comments.
I've just noticed typo in my own proposal s/There my/There may/.
And just one more question, why you propose to use SHOULD in "... the first
occurrence SHOULD be processed ..." Would MUST be more appropriate here? Or
you envision that in some circumstances this policy may be changed?

Regards,
Greg
