The real difference between the use of mailto versus INDP is that mailto is for
a receipient who does not have an IPP/INDP enabled client or does not have it
running at the time the notification is to be received.

I accept that INDP may "work" in the Internet if properly configured. But,
in this case, you wouldn't necessarily need to mandate mailto for human
readable. So either association (mail/human - indp/machine  OR  mail/inter
- indp/intra) is equally flawed.

Then... the only thing certain is that mailto is NOT intended for machine
readable. Why don't we just state that?

Peter Z. has a suggestion for helping to determine what is supported.

I fail to see the reason to ASSUME that every implementation of IPP
NOTIFICATION
will occur behind a firewall that is NOT configured to allow INDP
notifications
to pass through it.  Any attempt to associate "mailto" or "indp"
EXCLUSIVELY
with either INTERnets or INTRAnets is flawed.  If we would have used this
argument for IPP in the beginning we would have made statements like:

1. If a device is configured to print across the Internet it IS OUT OF
LUCK.
2. If a device is configured to print in the context of an Intranet it
MUST
support IPP.

Let's separate the issue of the INTERNET vs INTRANET context of these
delivery
services.  When a customer decides they want these services, they will
configure
their firewalls (if present) to make it happen.

I feel a more accurate way of looking at it is:

1. If a device is configured to provide event notification across the
Internet it MUST support mailto
2. If a device is configured to provide event notification in the context
of an Intranet it SHOULD support INDP

We could live with the proposal to bind human/mail vs. machine/indp.
However, this ignores the fact that INDP also handles human readable.

Following the SF meeting I would like to formally propose the following.

1. If a device wants to expose human readable events then it MUST support
the
mailto method

2. If a device wants to expose machine readable events then it MUST
support the
INDP method

But we do not UNCONDITIONALLY require either.
