RealObjects has released PDFreactor 2.0.1544, a $2494 payware "formatting processor for converting XML and XHTML/HTML documents into PDF. It uses Cascading Style Sheets (CSS) to define page layout and styles" which distinguishes it from most other similar solutions which are based on XSL. SVG is also supported, and XSLT fits in somehow I don't quite understand. New features in this release include .NET and PHP APIs, HTML form and Acroform support, CSS namespace selectors, data URIs, tagged PDF, CMYK colors, 2D barcodes, images in generated content, and resizing of background images.
