The syntax is that of email headers (key-value pairs, at the beginning of the page, separated from the main text by a newline): Author: Me Subject: My personal musings Blortnaz: Whatever you want to put here And now begins the main text ... This is not quite what you asked for, but it may serve your purpose, depending on what use-case you had in mind.
