The ActivateReferenceByScan Command ist used to set references on target content via scanning. The command can be used when the source content object is present in the current context. Once the command is triggered, the scan page opens up and the user can scan for an optical marker. Once an object was found, this object wil now reference to the source object, which the command was called from. If the user cancels the scanning, the reference will still stay active and can be set maually (e.g. in the case the target object could not be found due to a damaged optical marker).
