You can test for the Action Session Mark by checking the action's state. + The state is a dicionary whose "active-user" key yields the current + session's owner's username. If it matches the username in this menuitem's + "target" attribute, show the Active Session Mark. + + 2. The icon is stored in the menuitem's "icon" attribute. If none is set, + the client should use a fallback icon such as "avatar-default." + + 3. The name is stored in the menuitem's "label" attribute. + + 4. You can test for the Logged In Mark by checking the action's state. + The state is a dictionary whose "logged-in-users" key will give + an array of usernames. If the array contains the username in this + menuitem's "target" attribute, show the Logged In Mark. + +== The Guest switcher has "x-canonical-type" set to "indicator.guest-menu-item" + action. Its four visual components are determined by: + + 1. You can test for the Active Session Mark by checking the action's state. + The state is a dictionary whose "is-active" key yields a boolean. + If the boolean is true, show the Active Session Mark. + + 2. The guest user should use a fallback icon such as "avatar-default." + + 3. The name ("Guest") is stored in the menuitem's "label" attribute. + + 4.
