Hi

I am sorry, I don't know the appropriate terminology.

Could be used

*************** END

or a different special string, to end any headline scope? Like an "end parenthesis" for the headline just above it.

Maybe in this way, all headlines would be the same: if the special string appears, the headline scope ends there (inlinetask). If no special string, the scope would end before the next headline (or at the end of the document).
