minor typo in 3rd last bullet of "2.10 Practical Support: aria-label, aria-labelledby and aria-describedby"

[sasgrw]

Don't use aria-label or aria-labelledby on a span or div unless its given a role.

I think "its" should be "it's", "unless it is given a role".

Note, this typo does not exist in the current editor's draft.

Ah, I see. The editor's draft is quite different for that section. Thanks for the update.
