I don't see any concept of tick marks in ARIA.

The proposed Note mapping HTML5 semantics to native accessibility APIs should
cover the mapping of native sliders, including option labels.


Submitted to the editors of that draft as Bug 11003.

HTML5 defines conformance requirements for what semantics a user agent can
extract from what bytes, not what user interface it chooses to place on top of
those semantics.

I believe that's the correct approach, personally, but feel free to challenge
it. I recommend doing so on a mailing list or a dedicated bug rather than in a
narrow bug like this, since it would be a significant and deeply controversial
shift of approach.

I'd hope it would be uncontroversial for the spec to include an example of a
suggestion list with labels being used with input type="range", however.

I've opened a request for such an example as Bug 11004.

Orientation should be specified with CSS. Please submit such feedback to CSS
WG, rather than in a bug on the HTML spec.

Note that WebKit have already added CSS for making native-look sliders
horizontal or vertical:
