thanks for the feedback! We have been rather busy during the past week with
some other issues, but I will look over your points in the coming days and
respond in detail.

The editorial points look like they can be handled through minor textual
changes or clarifying emails. The substantive look like they may need
discussion at an (online) meeting.

The Accessible Platform Architectures WG has reviewed the Input Events
specification (https://www.w3.org/TR/input-events/) and has the following

== Substantive ==

1. From an accessibility perspective the following would be valuable:
- A notification to ATs that functions like text insertions were completed
so that positive reinforcement could be provided to the user.
- A programmatic way for alternate input solutions to drive some of the
changes would be helpful. For example, an AT might want to insert the text
now that this can be done in a device independent way. Some of this may be
provided for in UI Automation (Windows platform) but are they provided on

== Editorial ==

Editorial comments are less critical to handle on a WG-to-WG level, but our
participants thought they were relevant enough to send.

1. This text is not clear:

The DataTransfer object's drag data store item list
contains one entry with the draf data item type string
"text/html", whose kind
is *Plain Unicode string*, and whose data is a HTML representation of the
content that is in the clipboard, in the kill buffer
<https://www.w3.org/TR/input-events/#dfn-kill-buffer>, to be dropped or
otherwise the content that is to be added. [HTML-LIVING

Are you equating the kill buffer with the clipboard? It looks like you are
missing an “or” as in “ or in the kill buffer”.

2. Also, you refer to HTML-LIVING. Wouldn’t you be referring the W3C spec.
vs. the WhatWG version? This is in multiple locations in the spec. APA
notes this because of the better focus on accessibility within the W3C HTML

3. Another seemingly editorial issue is this text:
"A user agent <https://www.w3.org/TR/input-events/#glossary-user-agent>
*MUST* dispatch <https://www.w3.org/TR/uievents/#dispatch> [UI-EVENTS
<https://www.w3.org/TR/input-events/#bib-UI-EVENTS>] this event immediately
after the DOM has been updated due to a user expressed intention to change
the document contents which the browser has handled.”

This does not read properly. Maybe UI-EVENTS should come after “this event”

4. The beginning of this document should state that this is a solution
solely targeted at contenteditable elements in HTML vs. being a general
device independent solution. This will not work for SVG.

For APA,
