+         * - If there are single-quoted or unquoted attributes they will be double-quoted in the output.
+         * - If there are named character references in the attribute values they may be replaced with their direct code points. E.g. `…` becomes `…`.
+         * In the future there will likely be a mechanism to copy snippets of HTML from
+         * one document into another, via the HTML Processor's `get_outer_html()` or
+         * equivalent. When that happens it would be appropriate to replace this custom
+         * code with that canonical code.
