Conditional processing, also known as profiling, is the filtering or flagging of information based on processing-time criteria

DITA provides several attributes that can be used to add metadata to an element, for example specifying the platform or audience that a particular paragraph applies to. These metadata values can then be leveraged by any number of processes, including filtering, flagging, search, and indexing, rather than being suitable for filtering only.

For DITA 1.0, the list of metadata attributes that can be used for conditional processing is limited to:

• audience
• platform
• product
• otherprops
• rev (for flagging only)

There is a proposal for DITA 1.1 that will enable specializers to define their own metadata attributes for use in conditionally processing content.
