Conditional processing

Conditional processing is the filtering or flagging of information based on processing-time criteria. Conditional processing is based on attributes specified in the DITA source.

About conditional processing
Certain concepts are critical for a full understanding of conditional processing.
Expectations for conditional processing
Certain behaviors are expected of processors when working with conditional processing.
About the DITAVAL document
A DITAVAL document specifies a set of rules that defines which elements to include, exclude, or flag.
Conditional processing attribute values
Conditional processing attributes use space-delimited string values or grouped string values to support both filtering and flagging.
Conditional processing attribute values with groups
For more advanced needs, groups can be used to organize metadata into subcategories within a conditional processing attribute.
Conditional processing and subject schemes
When a subject scheme defines controlled values for an attribute, a processor can make use of that scheme for conditional processing.
Filtering based on metadata attributes
When rendering content, a conditional processing profile can be used to specify whether an element's content is filtered based on its conditional processing attributes.
Flagging based on metadata attributes
When rendering content, a conditional processing profile can be used to specify whether an element's content is flagged based on its conditional processing attributes.
Examples of conditional processing
This section provides examples that illustrate the ways that conditional processing attributes can be set and used.
