Hey all,


Thank you for the awesome carousel discussion today. I just pushed the
following changes to the feature branch:


*	Revised language throughout the pattern so that auto rotation is not
*	Removed use of term "horizontally scroll".
*	Simplified wording of first paragraph.
*	In second paragraph about importance of rotation control:

*	Added sentence about properly hiding content.
*	Clarified description of auto rotate consequences.

*	Changed rotation control requirements list:

*	to unordered list.
*	to list essential elements first.
*	To put auto-rotation related requirements in conditional sublist.

*	In Terms, added slide to the definition list.
*	In keyboard requirements, added note saying to not move focus when
activating the prev/next/auto-rotate controls.
*	In states and properties, added optional aria-live guidance to basic
carousel section.


One question: In a grouped carousel, Should aria-disabled or aria-current be
used for the picker button that corresponds to the displayed slide. What I
have in the draft now is:


"The picker button representing the currently displayed slide has the
property aria-disabled set to true. Note: aria-disabled is preferable to the
HTML disabled attribute because this is a circumstance where screen reader
users benefit from the disabled button being included in the page Tab


I was leaning toward aria-disabled because I am assuming that activating the
button probably does nothing. It's not like you can "reload" a slide. On the
other hand, this use case precisely fits the definition of aria-current.
Using both current and disabled at the same time would be quite verbose and
kind of overkill.
