/**
 * A crosswalk to ignore and dispose of the ingested material.
 * <p>
 * Specify this crosswalk in the mapping of e.g. METS metadata field
 * types to crosswalks when you wish to ignore a redundant or unknown
 * type of metadata.  For example, when ingesting a DSpace AIP with an
 * AIP ingester, it is best to ignore the rightsMD fields since they
 * are already going to be ingested as member bitstreams anyway.
