These remarks seem fairly off-topic for this bug, which is solely about
providing an example rendering.

As far as I can tell, the "value" attribute concretely maps the suggestion
label to its numeric value.

If this is somehow not sufficient, please file a separate bug explaining the
problem.

The requirement for accessibility mappings in the mappings Note is already
logged as Bug 11003.

ARIA does not cover all semantics that need to be mapped to accessibility APIs
(at the moment, for instance, it doesn't even cover tables). I don't think ARIA
has any particularly obvious mapping for range control suggestion labels.
Notably the JQuery UI slider doesn't seem to add ARIA annotations to the tick
mark labels.

If you think there is a good way to map the native semantics to ARIA as it
stands, please explain how in dedicated bug. Otherwise, please propose
additions to ARIA to PFWG via the public-pfwg-comments mailing list.
