Which item is NOT associated with creating templates using the template editor?

The item that is not associated with creating templates using the template editor is defining access rights. When working within a template editor, the primary focus is on the design aspects involved in building a template, such as designing layout, adding content fragments, and creating reusable components. These tasks directly relate to the visual and structural configuration of a template, enabling users to establish how content will be presented.

Defining access rights, on the other hand, falls under user management and security practices, which are essential for determining who can view or edit templates but does not involve the core functionality of the template creation process itself. Therefore, defining access rights is an administrative aspect that occurs outside of the template editor's more creative functions.
