I have to transform this into xsl:fo ! so, i do really NEED the additional break here! background is- i am tranforming a Lotus Notes XML Export into a PDF Dokument. Some linbreaks and Paragraphs don't "get through" my templates at the moment. I am trying to figure out what's wrong or try to find a workaround, so that the output looks like the Notes document. I will try to see if your hints get me any further. Thanks, Sascha ----- Original Message ----- From: "G.
