---

Buttons should use the dsBtnDisabled directive instead of the HTML disabled attribute. This should be done to ensure that users with a screen reader are able to understand that the a button button is present, and that it is disabled. The native html disabled attribute does not allow users to navigate to the button by keyboard, and thus they have no way of knowing that the button is present.
