The main scenario for using this property is if you are serving DRM-protected content and wish to override the LicenseAcquirer to provide custom license acquiring behaviors such as adding business data or authentication tokens to the license request. See Digital Rights Management (DRM) for more information.
A LicenseAcquirer can only be associated with one MediaElement at any given time. Attempting to set a LicenseAcquirer already associated with one MediaElement on another MediaElement will throw an error.
