From there, an FO processor determines how to position the text within the boundaries described by the FO document.

Instead, it describes what the pages look like and where the various contents go. It does not definitively describe the layout of the text on various pages.

It allows for the automatic generation of a table of contents, linked references, an index, and various other possibilities.Īn XSL-FO document is not like a PDF or a PostScript document. The XSLT transformation step is exceptionally powerful. Even tutorials on XSL-FO tend to be written with XSLT commands around the FO processing instructions. This transformation step is taken so much for granted in XSL-FO that it is not uncommon for people to call the XSLT that turns XML into XSL-FO the actual XSL-FO document itself. The XSLT language itself was originally conceived only for this purpose it is now in widespread use for more general XML transformations. The most common output of XSL-FO is a PDF file or as PostScript, but some FO processors can output to other formats like RTF files or even just a window in the user's GUI displaying the sequence of pages and their contents. FO processors convert the XSL-FO document into something that is readable, printable or both. Once the XSL-FO document is generated, it is then passed to an application called an FO processor. This XSLT transform converts the XML into XSL-FO. Then, the user obtains an XSLT transform, either by writing one themselves or by finding one for the document type in question. XHTML, DocBook, and TEI are all possible examples. The general idea behind XSL-FO's use is that the user writes a document, not in FO, but in an XML language. And, unlike CSS which modifies the default presentation of an external XML or HTML document, it stores all of the document's data within itself. It has no semantic markup as this term is used in HTML. Unlike the combination of HTML and CSS, XSL-FO is a unified presentational language.
