The subfield Name functions the same way it does for Headers to Add/Replace.
N/Ax-content-age

Use '-' (dash) instead of '_' (underscore) in header name as '_' is ignored and the header is not captured.  '-' is internally transformed to '_' for you to map to the Pipeline parameter. For example, HTTP-ACCEPT instead of HTTP_ACCEPT.
