The following the figure extension:
A figure can be defined by using a pattern equivalent to a fenced code block but with the character
^^^ This is a figure ^^^ This is a *caption* . <figure> <p>This is a figure</p> <figcaption>This is a <em>caption</em></figcaption> </figure>
A footer equivalent to a block quote parsing but starts with double character ^^
^^ This is a footer ^^ multi-line . <footer>This is a footer multi-line</footer>
A cite is working like an emphasis but using the double character ""
This is a ""citation of someone"" . <p>This is a <cite>citation of someone</cite></p>
