After defining the standards for a project, you need to enable them to make them active within the project.
While you are still working on setting up the standards for a project, you might not want the standards to be activated in the project right away, as standards styles might still be added, removed, or changed. Once the setup is complete, however, you must enable the standards for the project.
The selected synchronization behavior (automatic, semi-automatic, or manual) is now activated.
