FOP is the world's first print formatter driven by XSL formatting objects. It is a Java 1.1 application that reads a formatting object tree and then turns it into a PDF document. The formatting object tree, can be in the form of an XML document (output by an XSLT engine like Xalan) or can be passed in memory as a DOM Document or (in the case of Xalan) SAX events.
