ARIA1: Using the aria-describedby property to provide a descriptive label for input controls

Refer URL: http://www.w3.org/TR/2012/NOTE-WCAG20-TECHS-20120103/ARIA1
Note the statement made under 'User Agent and Assistive Technology Support
Notes' which states that IE 8 does not support aria-describedby at all. I
tested the aria-describedby property using JAWS 13 and IE 8 and it did work
barring minor issues. Therefore, I question the credibility of this
statement. Note that in IE 8, the aria-describedby property on the text
programmatically tied to the control is spoken twice (which could be due to
the use of landmark roles).

Proposed Change: Change the latter part of the sentence to read, "IE 8
partially supports aria-describedby ..."
