Darwin Information Typing Architecture (DITA) is an XML standard defined specifically for technical documentation. This standard provides a topic-based authoring structure around information types such as task instructions, conceptual topics, and reference materials. In addition, it supports a wide variety of outputs and formats through information mapping schemes. Within DITA, you can add specialized vocabularies, thus giving your authors the freedom to express semantic ideas. Finally, all standard DITA tools can process your content even with your proprietary elements added.
