Metadata attributes
Certain attributes are common across most DITA elements. These attributes support
content referencing, conditional processing, application of metadata, and globalization and
localization.
Conditional processing attributes The metadata attributes specify properties of the content that can be used to determine how the content should be processed. Specialized metadata attributes can be defined to enable specific business-processing needs, such as semantic processing and data mining.
Translation and localization attributes DITA elements have several attributes that support localization and translation.
Architectural attributes The architectural attributes specify the version of DITA that the content supports; they also identify the DITA domains, structural types, and specializations that are in use by the content.
