mappings-01 and the general procedure

[Shawn Steele]

I think that 2003 compatibility should be the default.

If that can't be agreed upon, then I think that mappings should at least say how to do a 2003 mapping mode for apps that need it

this point might be elaborated by recognizing that IDNA2008 IS
different from IDNA2003 and that mapping is one of the differences. If
similarity to IDNA2003 is a useful metric, then the outlined mapping
might be done in a different order.
