Hello Ken,

Do you have any idea how the equivalence and compatibility
decompositions currently in the Unicode spec were arived at?
I started writing a normalization document for the context of
identifiers (URLs,...), and my take for this would be somewhat
between equivalence and compatibility. For this I would like to
know how the current distinction was arived at, and based on what,
and who did it. Any information appreciated. If you think you need
to ask a wider audience, please feel free to post on unicore, or
ask me to do it.

Regards, Martin.
