Now that you give a solution with \definetextbackground (the solution below), I would like to point out that with this definition the beginning of the highlighted text does not have the upper frame turned on, while at the end the bottom frame is turned on (of course this is what we want). So my question is: can one have both the upper frame turned on at the begining of the highlighted text (and only there) and also the bottom frame turned on at the end (and only there). In other words, a highlighted framed text spanning over two (or more) pages, would be like a big rectangle of which the upper and the bottom frame, as well as the left and right frames, are shown.
