XSL-FO Extensions in Xml2PDF

XSL-FO is a primary input format for Xml2PDF. Being properly designed it covers most of the publishing workflow requirements. Yet, there are some special PDF features that are missing in the XSL-FO specification. Altsoft does its best to cover the customers' needs and provide some extensions to XSL-FO format syntax.

Namespace

All extensions are defined in the namespace "altsoft:". To use any of the Altsoft extensions, add a namespace entry for http://alt-soft.com/xml2pdf/extensions either to the root element or to any parent element:

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format"
	xmlns:altsoft="http://alt-soft.com/xml2pdf/extensions">
     

Extensions:
