Thanks Luigi!
Your solution works as intended when the framed, highlighted text with background spans over two pages (though it doesn't when it spans over three pages or more, but this is not a real issue, since it is a bad idea to have such long highlighted texts…).
Best regards: OK
I copy below your modfied solution:
