Import content or zafu in zazen text

For example:

------------------ zazen content (v_text)
List of recent changes:
{{render "Node-changes"}}

Import and zazen parse a title from another element:
{{zazen project.title}}
------------------

Again: RubyLess could be used to safely 'eval' the code between "{{" and "}}". Context in eval could keep track of evaluated node attributes to avoid recursion.
