Harry,

My view is that the mailto notification is bound to human readable. The
mailto method is bound to a standard application that presents notification
content to a human for interpretation and consumption.  INDP may contain
octets that a human can decipher.  The consumer of the content is an
application and the application is responsible for interpreting the content.

I resist binding mailto to Internet and INDP to intranet.  I see no reason
that INDP would not be used on the Internet.  It should be a site specific
policy decision to allow INDP or IPP through a firewall.

As I stated before I favor a notification being sent out at INDP
registration.  That allows a notification recipient to determine if the
infrastructure supports INDP notification.

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.
