- xml in not an input format but (a well structured) interchange format.
XML is a very good master format from which to derive all outputs. For example, I receive wordprocessor files from academics and convert them to XML by a combination of automated processes and hand-tagging. The XML is then stored and maintained as the master version of that document, and when we need to produce a new release in HTML, PDF or eBook, a new style of PDF, a text version optimised for screen-readers, etc. we take a snapshot of the latest XML and run it through batch production processes - including ConTeXt for the typesetting side of things. That might be overkill for small projects (we're currently holding 25 million words in XML), but the principle applies no matter what size of content you have. Duncan
