ARIA in HTML

It is NOT RECOMMENDED to use aria-disabled="carview.php?tsp=true" on an a element with an href attribute. If a link needs to be "disabled", remove the href attribute.

test case

<a href="..." aria-disabled=true> should be flagged as a warning
while
<a role="link" aria-disabled="carview.php?tsp=true"> should continue to be valid.

ARIA 1.2 note for aria-disabled referencing it is ok to mark role=link as disabled, but advising not to do so for host language inks (a with href)

While aria-disabled and proper scripting can successfully disable an element with role link, fully disabling a host language equivalent can be problematic. Authors are advised not to use aria-disabled on elements that cannot be disabled through features of the host language alone.
