Hatnote templates are actually broken, incorrect wikitext. They create code sections that are extremely difficult to parse because neither the top nor the bottom template is "syntactically complete" - each is but one half of a wikitext idiom (or program, if you like).

Flow has built-in functionality that replaces hatnotes.
