Sifting through my TeX-mailbox, I came along this post of Wolfgang Schuster and decided to try all variations given to the align parameter on \framed.
Curious in which cases the \hbox and in which the \vbox is chosen, not unimportant of course.
I did this by typesetting \hbox{abc}\hbox{xyz} inside a framed. For \hbox want expects abcxyz as output and for \vbox abc and below it xyz. As can be seen in the first two examples.
To my surprise none of the \framed[align=..] options exhibits \vbox character!

Thus my question: has the behaviour of \framed[align=..] changed in the mean time? Three years is of course an eternity when seen in the perspective of the speed with which ConTeXt is evolving 😃. Or is there another reason why the \vbox effect is not shown in any of the examples?
I am enclosing a minmal example and its output. Just curious.

Why does the [align=middle] makess such a difference?

\framed can use a \hbox or a \vbox to place the content, by default it uses a \hbox
but when you set the correct value for the align key it uses a \vbox.
