However, within the United States, this component may be useful in solutions to comply with U.S. Office of Federal Contracts Compliance Programs (OFCCP) regulations. U.S. OFCCP require contractors to maintain a record of positions for which searches of external candidate databases were conducted, and for each search, "the substantive search criteria used."

Document Identification Group. Details
Provides the Identifier(s) of the document being communicated. Uniquely identifies a Document within an organization. Typically there is only an ID for a document within one system. However, in the case of B2B transactions the different parties to the transactions may have different Identifiers for the same document. This construct is designed to allow for these different identifications. This type is based on the Star Standards Document Identifier Group.
The contextual meaning of a particular DocumentIDGroup will be determined by its fully qualified XPATH. For example: ScreeningOrder/DocumentIDGroup/DocumentID
