PegaWAI ruleset deprecated in 8.5
Valid from Pega Version 8.5
Accessibility functions that were contained in the PegaWAI ruleset are now integrated into the main Pega Platform™. Consequently, the user interface in your applications now features accessibility functions out of the box, so you no longer need to use the PegaWAI ruleset to ensure accessible behavior in your application.
