I would very much like to have these as two separate issues.

That said: I am very concerned that the real-world examples we've 
presented for item [a] will be discarded in the process.
It is absolutely critical that [a] include caret browsing and text 
selection.

If it is removed from the scope of [a], then we are once again lost.

As for item [b], I think it's quite important to open it as a new issue.
Item [b] brings up IME, which item [a] does not.

That's a really important distinction and merits its own issue and CP 
process.

BOTH of the issues require caret browsing and text selection.

EVERYONE should be aware that these are abstractions based on decades of 
precedent. They are analogous to mouse events and keyboard events. It's 
entirely possible that pointer events come from something other than a 
mouse and that keyboard events come from something other than a 
keyboard. It's entirely possible that focus events come from something 
other than pointer and keyboard events. And it's entirely possible that 
caret browsing and text selection would be used for items that are not 
considered "text" in the standard meanings of using a system provided font.
