RenderX XEP is a commercial-grade application written in Java for dynamic rendering of XML documents. XEP is a pluggable architectural component that takes two open standard inputs, XML data and XSL FO stylesheet, and produces the industry's defacto standards for high-quality rendered electronic documents, Adobe PDF, and PostScript. XEP supports many extensions to the XSL FO Specification, including SVG graphics and PDF-to-PDF linking.
