Meta Courses tracking

If you put the AttendanceRegister instance in a "meta-course" (i.e. a Course having Course meta link enrolment with other Courses), pay attention to the Attendance Tracking Mode setting.

If you set Attendance Tracking Mode to "This Course only", you are instructing the Register to track only activities taken in THIS Course, and tracked Users will be Users from linked Courses too.

If you set it to "All Courses linked by Course meta link", the Register will also track activities in the linked Courses.

---

The reason is that AttendanceRegister tracks Users with mod/attendanceregister:tracked Capability in Tracked Courses. In a Meta-Courses, Roles (and Capablities) may be merged from the meta-linked Courses. So, for example, a Student in a meta-linked Course is also a Student in the Meta-course.
