Printing XML: Why CSS Is Better than XSL "The disagreement starts with how best to express all this. Walsh's solution is to write a 1000-line XSL transformation that generates XSL-FO, which is subsequently turned into PDF. We will argue that it's much easier for most authors to express styling in CSS; in the case of the WebArch document, one can reuse the existing CSS stylesheets (200 lines or so) and add some print-specific lines. And, although browsers tend to focus on dynamic screens rather than on printing, products like Prince happily combine CSS with XML and produce beautiful PDF documents."
