        The field list should be at the start of the document,
        and will then be converted to a `docinfo` node during the
        `docutils.docutils.transforms.frontmatter.DocInfo` transform (priority 340),
        and bibliographic keys (or their translation) will be converted to nodes::

            {'author': docutils.nodes.author,

        Also, the 'dedication' and 'abstract' will be placed outside the `docinfo`,
        and so will always be shown in the document.

        If using sphinx, this `docinfo` node will later be extracted from the AST,
        by the `DoctreeReadEvent` transform (priority 880),
        calling `MetadataCollector.process_doc`.
        In this case keys and values will be converted to strings and stored in
        `app.env.metadata[app.env.docname]`

        See
        https://www.sphinx-doc.org/en/master/usage/restructuredtext/field-lists.html
