Changes

If you want to get more from your code than just a PDF (or DVI) output, e.g. HTML, or if you need a good typesetting machine for your XML code, you're right with ConTeXt. Handling XML in ConTeXt has improved dramatically with the advent of MkIV. A new infrastructure, based on Lua, makes typesetting, manipulating, filtering, and reusing XML much much easier than before. Unfortunately, this means that most of the existing documentation is now obsolete. As a rule of thumb: in In general, the "old" MkII code uses upper-case <tt>XML</tt> in its commands, the new MkIV code uses lower-case <tt>xml</tt>.
