[HTML AAM] name computation issues for input=type

Hi, I have bunch of comments regarding to accessible name computation for
input=type controls.

5.1.1 I think aria-placeholder should go right after placeholder.

5.2.1 "If steps 1 to 2 do not yield a usable text string" -> "Otherwise".
Also these two may be combined into "Otherwise use visual label if provided
** localized "submit" value for input@type="submit", ** localized "reset"
value for input@type="reset".

5.2.2 I'm not sure whether @value should be used as button description.
Visual label usually doesn't provide description.

5.3.1 "Otherwise the user agent may provide an accessible name via a
localized string of the phrase "Submit Query" -> "Otherwise use visual
label on the control if provided by the user agent." If it's not clear
enough then "For example, the user agent may provide localized version of
"Submit Query" phrase".

Thanks!
Alexander.
