implementation/stability status of various new ARIA 1.1 roles/attributes

hi all,

Am interested in finding out status of the various attributes/role values
added in ARIA 1.1. (current editors draft)

Currently the W3C validator flags the following as errors, which of them is
stable/implemented?


   - aria-describedat
   <https://rawgit.com/w3c/aria/master/aria/aria.html#aria-describedat>
   - aria-current (state)
   <https://rawgit.com/w3c/aria/master/aria/aria.html#aria-current>
   - aria-roledescription
   <https://rawgit.com/w3c/aria/master/aria/aria.html#aria-roledescription>
   - aria-errormessage
   <https://rawgit.com/w3c/aria/master/aria/aria.html#aria-errormessage>
   - aria-modal
   <https://rawgit.com/w3c/aria/master/aria/aria.html#aria-modal>
   - aria-placeholder
   <https://rawgit.com/w3c/aria/master/aria/aria.html#aria-placeholder>
   - aria-colcount
   <https://rawgit.com/w3c/aria/master/aria/aria.html#aria-colcount>
   - aria-colindex
   <https://rawgit.com/w3c/aria/master/aria/aria.html#aria-colindex>
   - aria-colspan

   - aria-rowspan
   <https://rawgit.com/w3c/aria/master/aria/aria.html#aria-rowspan>
