DITA processing

Several common DITA processing behaviors are driven by attributes, including navigation, content reuse, and conditional processing.

1. IDs and references
   The DITA identity attribute provides mechanisms for identifying content for retrieval or linking. The syntax for referencing IDs is consistent regardless of the referencing mechanism.
2. Navigation behaviors
   The following behaviors support the creation of reader navigation to or across DITA topics.
3. Content inclusion (conref)
   The DITA conref attribute provides a mechanism for reuse of content fragments. The conref attribute stores a reference to another element and is processed to replace the referencing element with the referenced element.
4. Conditional processing (profiling)
   Conditional processing, also known as profiling, is the filtering or flagging of information based on processing-time criteria.
5. Chunking
   Content may be chunked (divided or merged into new output documents) in different ways for the purposes of authoring, for delivering content, and for navigation. For example, something best authored as a set of separate topics may need to be delivered as a single Web page. A map author can use the chunk attribute to split up single documents into component topics or combine multiple topics into a single document as part of output processing. When a set of topics is transformed for output using a map, the map author may use the chunk attribute to override whatever default chunking behavior applies. The chunk attribute allows the map author to request that multi-topic documents be broken into multiple documents, and that multiple individual topics be combined into a single document.
6. Translation
   DITA has specific capabilities for preparing content for translation and working with multilingual content, including the xml:lang attribute, the dir attribute, and the translate attribute.
