Requirement 9 /req/core/fc-md-links mentions that the link array "SHALL include an item for each supported encoding with a link to the collection resource (relation: item)." but example 3 seems to use "rel": "about" for that purpose. https://raw.githubusercontent.com/opengeospatial/WFS_FES/master/core/openapi/schemas/collectionInfo.yaml does use rel: item in the example.
