Editable templates have been introduced to:
1. Allow specialized authors to create and edit templates .
Such specialized authors are called template authors
Template authors must be members of the template-authors group.
2. Provide templates that retain a dynamic connection to any pages created from them. This ensures that any changes to the template are reflected in the pages themselves.
3. Make the page component more generic so the core page component can be used without customization.
With editable templates, the pieces that make a page are isolated within components. You can configure the necessary combinations of components in a UI, thereby eliminating the need for a new page component to be developed for each page variation.
