GitHub: _[$1](https://github.com/artdecocode/$2)_
</details>

<!-- Now use the macro! -->
%USE-MACRO example
<data>Documentary</data>
<data>documentary</data>

Currently, a macro can only be defined in the same file as its usage. Also, in future, macros will improve my allowing to use named placeholders.
