Following are a few comments on Ian Jacob's (IJ) memo [2]. Other related
comments are in [1].

My comments are marked with "EH:".

EH: This seems to be a new concept, this idea of "prompt" being reserved for
a particular UI approach, but that we don't attempt to define it. I find
this problematic because not having agreed-upon definitions usually leads to
problems. For example, this approach begs the question as to what
constitutes a "UI approach". For example, do a picture and
visually-displayed text count a single UI approach (because they are both
"visual") or as two approaches (because they are useful for different
disability groups)? I really don't see why "prompt" should be treated
differently than any other unrendered (or pre-rendering) content: If it is a
non-text content (and it isn't secondary content) then it needs a text
equivalent and all checkpoints pertaining to text equivalents apply. Beyond
that, _if_ there are special classes of content (alerts, notifications,
prompts, indications (?), repair text, etc.), that need to be treated
differently, then we need to have checkpoints that provide that guidance.
See [1] for further discussion.
