Review Comment:
   Maybe rather `get`/`add` semantic names?

Review Comment:
   You see a way to throw ISE if the documented condition is not met?

Review Comment:
   In DI we use the term priority. Maybe that be suit here too? This making the 
terms consistent while `Integer.MAX_VALUE` would be the highest one?
   
   Comment talks about order, but method name is rank...

> In markdown document add:

> {code}
> Then anchors generated by toc macro looks like: {{#Your_First_Mojo}}
> and anchors generated by skin looks like: {{#your-first-plugin}}
> - Doxia Site Renderer 2.0.0-M4
> - Fluido Skin 1.11.1
> Tested on Maven main site without more investigate.
