Hoverable condition for Content on Hover or Focus

Hi James,

I wanted to respond to your objection to the latest CFC language:
> The hoverable statement makes no sense and needs revising. I don't understand what "hover the additional content". Does it mean "The additional content remains visible while the pointer is over the additional content"?

Yes, that's exactly what it means.  A previous iteration said something similar to your suggestion and I cannot recall why it was changed at the moment, but coming up with a way to state this condition that no one finds confusing has been a bit of a challenge.  I did my best to explain this condition in detail in the draft Understanding<https://rawgit.com/w3c/wcag21/content-on-hover-or-focus/understanding/21/content-on-hover-or-focus.html>, and there's also Example 2 to visually show the importance.  (Note I still need to update from Visible Trigger to Dismissable in the understanding, but the rest is applicable.)

Can you live with this knowing we can work on this editorially?
