Hello Charles,

The current (to be resubmitted in a couple hours)
draft-duerst-mailto-bis-01 already forsees that the left hand
side of a mail address may be internationalized in the future.
What we currently say is that this is reserved for future use,
but will be encoded in UTF-8 in the mailto URI for compatibility
with IRIs.

This means that if you have a mailer that has the downgrading
features discribed above, it should work. (Of course, these
downgrading features don't exist yet.)

If you are looking for an URI scheme that says "mail to a@b.c,
but if you can't do that, mail to d@e.f", then such an extension
could be built into the mailto URI scheme, but then again,
such an extension would be similarly valuable for other schemes.
So why no propose a new scheme, maybe let's call it the or:
scheme, which takes two (sufficiently escaped, with 'sufficiently'
still to be worked out) URIs, and tries the first URI first, and
if it doesn't succeed, tries the other URI. Could be pretty
handy in some cases, even with (or particularly with) mixed schemes.

So I don't see any need to change draft-duerst-mailto-bis-01.
But please tell me if you disagree.

Regards,     Martin.
