There are currently two documents for touch-action. It seems like there was an attempt to add a separate document for the lvl2 spec, and keep the original at lvl1.

Back in reality, the original document has been updated to lvl2, and the lvl2 document is not maintained, and is not shown publicly.

Someone needs to go through these and figure out what to do with them.
