Draft for Notifications

Colleagues:

We are advised our comments on the Push API specification would more
properly be addressed by the Notifications specification. Below is a
draft filing for your review and improvement.

Since the W3C Notification specification is not currently in active
development:
http://www.w3.org/TR/notifications/

We are advised by our colleagues in the Web Platforms WG to work with the WHAT-WG successor specification:
https://notifications.spec.whatwg.org/

Please provide any comments, and particularly sample API code for the
below.

<begin message>

The Accessible Platform Architectures (APA) Working Group at the W3C believes there
are significant use cases requiring API support for "Do Not Disturb"
functionality in various web applications, whether accessed via mobile
device or desktop browser. We are advised by W3C colleagues that the
appropriate locus for our feature request is the Notification
specification.

One such use case is the conclusion of a financial transaction where it
is critical that the key terms of the transaction can be completed
without distracting interruptions--which could also trigger timeouts
that would exaserbate the user's ability to complete the transaction.
The key juncture of a financial transaction might include the screen
where payment is finally authorized, a digital signature is applied, and
an accessible receipt is recieved.

Another use case is to prevent a list of items from scrolling while a
screen reader user is iterating through the list. Push actions which
result in scrolling exaserbate the user's ability to function smoothly
by causing the focus to shift outside the user's control.

We note this kind of functionality is available heuristically on mobile
platforms.  An example Android application providing similar
functionality is:
https://play.google.com/store/apps/details?id=com.tryagent

However, what is needed is the ability to temporarily suspend push
notifications via an API call, so that an application can invoke a "Do
not disturb" feature based on context, and so that users may gain easier
access to turning notifications on and off directly, whatever the
platform, without navigating multiple menus. 

We propose the addition of a section in support of this feature
requirement as follows:

Section 2.12 Defer and Queue

When this flag is set no notifications are delivered to the user
interface. Rather they are queued for display once the flag is cleared.
