Similar to the recently introduced source parameter in code macro I would like to do the same for the content macro to provide a safe way to insert wiki content, especially for script variables.
My plan is to use the same naming, syntax and logic as the one defined on https://extensions.xwiki.org/xwiki/bin/view/Extension/Code%20Macro/#HSource for users, but it would be a different component system behind the scene (mainly because the content would come with a default rendering Syntax instead of a default language).
Here is my +1.
