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.
