Missing media player design pattern

The Media Player design pattern within the WAI-ARIA 1.0 Authoring Guide has
no content:
https://www.w3.org/TR/wai-aria-practices/#mediaplayer

I'm pretty sure there used to be content, but now it appears to be empty
even in the historic archives.

Did I just imagine that the Authoring Guide had previously incorporated a
media player design pattern? It's possible that I'm thinking of the DHTML
Style Guide, but I was almost certain that had been incorporated into the
Authoring Guide and further refined:

My request is that you either:
a) Restore the lost content, or
b) Add a note explaining the status of this content.

Thanks,
Terrill
