Comments on the current IndieUI draft

I am in favor of the draft wanting to enable the detection of certain
assitisve technology software settings and features, however I think that
it does not go as far as it needs to to be of ultimate practical use.

5.4.1 Key: screenreader
Some platforms have only one viable screen reader (iOS) whereas others have
multiple (Windows). It is therefore not only important that a screen reader
is running, ut rather which one is running.

Also, whereas some operating system versions are closely synced with the
screen reader versions (iOS, OS X), other are totally independent
(Windows). Therefore it is also important to know which version of the
screen reader is running.

This key should therefore wither return an easily parseable string
representation of the screen reader and version, or it should return a JSON
structure with the appropriate information or undefined if not relevant.

This brings me to a second critique:

What about Voice Recognition and other Assistive Technology software
components? I see support for contrast issues, magnification and subtitling
(hearing issues) but I see no support at all for the types of assistive
technology used by users with physical disabilities. Dragon is one such
piece of software. The existence of this sort of technology should also be
exposed. This leads me to think that the key should be changed from
screenreader to assistivetechnology (or some such equivalent) in order to
be more widely usable and applicable. If the return type is a JSON
structure then it could include the type of assistive technology with
'screenreader' being one of the applicable types.

Furthermore, I would like the committee to consider whether the actual
capabilities of the assistive technology should be detectable, rather than
the existence of a particular version of the technology. This would
certainly require some careful thought to come up with a useful set of
features but some food for thought would be to specify for example which
ARIA roles are fully supported by the browser/AT combination, which ARIA
version is supported.

I am still reading through the entire draft and may have more comments later
