 * `document` is the highest level of content, so it’s not listed here.
 *
 * Containers in markdown come from the margin and include more constructs
 * on the lines that define them.
 * Take for example a block quote with a paragraph inside it (such as
 * `> asd`).
 *
 * `flow` represents the sections, such as headings, code, and content, which
 * is also parsed per line
 * An example is HTML, which has a certain starting condition (such as
 * `<script>` on its own line), then continues for a while, until an end
 * condition is found (such as `</style>`).
 * If that line with an end condition is never found, that flow goes until
 * the end.
 *
 * `content` is zero or more definitions, and then zero or one paragraph.
 * It’s a weird one, and needed to make certain edge cases around definitions
 * spec compliant.
 * Definitions are unlike other things in markdown, in that they behave like
 * `text` in that they can contain arbitrary line endings, but *have* to end
 * at a line ending.
 * If they end in something else, the whole definition instead is seen as a
 * paragraph.
 *
 * The content in markdown first needs to be parsed up to this level to
 * figure out which things are defined, for the whole document, before
 * continuing on with `text`, as whether a link or image reference forms or
 * not depends on whether it’s defined.
 * This unfortunately prevents a true streaming markdown to HTML compiler.
 *
 * `text` contains phrasing content such as attention (emphasis, strong),
 * media (links, images), and actual text.
 *
 * `string` is a limited `text` like content type which only allows character
 * references and character escapes.
 * It exists in things such as identifiers (media references, definitions),
 * titles, or URLs.
