some editorial feedback on WAI-ARIA Authoring Practices 1.1

In an effort to provide a friend with a pointer to the latest WD and where
to comment I encountered a few issues:

Latest editor's draft:
http://w3c.github.io/aria/practices/aria-practices.html link in the the 14
May 2015 WD (://www.w3.org/TR/wai-aria-practices-1.1/) points to a stale
version from last year. which has 724 instances of the word "undefined" in
it.
The WD also states

"In-progress updates to the document may be viewed in the publicly visible
> editors' draft <http://w3c.github.io/aria/practices/aria-practices.html>."


which also  to the aforementioned problematic editor's draft.

be good if the 'latest editors draft' pointed to the latest editor's draft.
