The following attributes are common across most DITA elements.
- Identity attribute
The DITA identity attribute provides mechanisms for identifying content for retrieval or linking.
- Content reference attribute
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.
- Metadata attributes
The metadata attributes express qualifications on the content. These qualifications can be used to modify the processing of the content.
- Miscellaneous Attributes
The xml:lang attribute identifies the language of a topic or content fragment. The outputclass attaches a classifying label to an element.
- Architectural attributes
DITA provides some attributes to provide type information to processors instead of qualifications or properties of content.
- Conditional processing
Conditional processing is the filtering or flagging of information based on processing-time criteria
