The author should supply values for aria-valuenow, aria-valuemin, and aria-valuemax, unless the value is indeterminate, in which case the author should omit the aria-valuenow attribute.

Also, there's still an open bug about indeterminate progress bars' state being reported incorrectly to assistive software: https://crbug.com/564278 .
