Why have DITA Customizations
DITA XML and DITA Open Toolkit DITA is an XML standard with a defined syntax or element structure that is supported by many XML authoring tools, such as Oxygen XML Author/Editor. Many organizations use XML authoring tools to write, edit, and review technical documentation. Although you can write DITA XML without such a tool, an XML authoring tool provides so many useful features, such as authoring support and automatic validation, that it is not worth it.
