This PR was merged into the 2.7 branch. Discussion ---------- Unify placeholders in documentation and code Update validation documentation to unify approach with placeholders.

I propose to update documentation to use `{{ value }}` placeholders Commits ------- 274ffc5 Unify placeholders in documentation and code
