    // Per the interface documentation of this method, the returned URI may
    // optionally also serve as the URL of a documentation page about this
    // field. However, Drupal does not currently implement such a documentation
    // page. Therefore, we return a URI assembled relative to the site's base
    // URL, which is sufficient to uniquely identify the site's entity type +
    // bundle + field for use in hypermedia formats, but we do not take into
    // account unclean URLs, language prefixing, or anything else that would be
    // required for Drupal to be able to respond with content at this URL. If a
    // module is installed that adds such content, but requires this URL to be
    // different (e.g., include a language prefix), then the module must also
    // override the RelationLinkManager class/service to return the desired URL.
