Two things here:

- We *have* discussed other mapping rules: see Mark's proposal from a few weeks ago at <http://www.alvestrand.no/pipermail/idna-update/2009-March/004199.html>.

- If you don't like the vagueness of the mapping rules being bandied about, and you don't like Mark's rather specific proposal, send in your own.
