Extra Elements

By default, dctap ignores elements that are not part of the DCTAP model. As explained in the section “Non-DCTAP elements are ignored unless configured.”, dctap can be configured to recognize extra elements as belonging either to a shape or to a statement template. In the absence of such configuration, dctap has no basis for handling a given element as a shape constraint or a statement constraint. Columns with unrecognized headers are simply ignored and passed through, unchanged to text, JSON, or YAML output.
