This visual debugging program for XSL stylesheets is based on the Altsoft Xml2PDF formatting engine. It takes an XSL-FO file or a pair of XML and XSLT files as input, follows XSL-FO formatting instructions and generates a PDF document as output. The resulting PDF file may contain layers for displaying boxes, baseline tables and breaks for the groups of FO objects and particular FO objects as well.
