Hi Telerik team,
Few of our clients reported the following issue with respect to WCAG 2.0 SC 4.1.2 standard. (508 Standard and compliance) -
|Ensure ARIA roles, states, and properties are valid||LI has an aria-level attribute of 0, which is not an integer value greater than, or equal to, 1|
Example: visit https://demos.telerik.com/aspnet-ajax/tabstrip/examples/wai-aria-support/defaultcs.aspx
Observe the ul-li elements created for tabstrip. On each li element, there is aria-level attribute whose value is set to 0.
As per WCAG this value should start from 1. The value 0 is invalid. Refer: https://www.w3.org/TR/WCAG20-TECHS/ARIA12.html
Please let me know when are you going to fix this for compliance.
