They are created automatically when an XQuery or XSLT document that specifies post-processing is dropped directly onto the XML pipeline canvas. You can also create one by dragging the XSL-FO icon from the s. The only property you can specify for an XSL-FO node is its name.

Input Port

XSL-FO nodes have a single input port that you use to specify the XML to be converted to PDF. This node expects XML defined using the FO grammar. You can specify a default value, or the value can be dynamic (the output from another node in the XML pipeline, for example). XSL-FO nodes are typically piped to XQuery and XSLT nodes, but they can be piped to any node that outputs XML using the FO grammar.

Output Ports

XSL-FO nodes have a single output port, used to specify what to do with the result of the transformation. Typically you use the Copy to URL property to write the output PDF to a file system, but you could also pipe it to a converter that does something with the PDF, or to a Pipeline Output node.
