Using {include} inside a page that sets an attribute (e.g. sets the page title) will override that attribute's value with whatever value is set in the included page.

Example: the title for the page below will be whatever the title is of the /news/recent.page instead of what is defined in the page itself

---
title: Welcome to Apache ServiceMix!
--- name:main pipeline:conf

[News]

{include:/news/recent.page}
