Style Sheets: CSS, XSL and CSS-OM

XSL templates can generate any XML elements (instead of formatting objects)
Very general transformations:
- Can generate elements, attributes, PIs, comments and text
  (no entities, doctype, CDATA)
- Generates XML Namespaces automatically
  (but no control over prefix or place of declaration)
Can be modular ("import" mechanism)
