-	  Provides maximum preferred interval to be used by a publisher for negotiation
-	  of the final maximum subscription report interval, after receiving a subscription
-	  request from the initiator. This value should be selected as a compromise between
-	  keeping the power consumption low due to not sending reports too often, and allowing
-	  the initiator device to detect the publisher absence reasonably fast due to not sending
-	  the reports too rarely. The current algorithm is to select bigger value from the one
-	  requested by the initiator and the one preferred by the publisher.
