Below is an example of the comm and description that indicates that the extent specified by the XTNT LST
param
eter is located in the center of Dataset 1,and thespecified extent in the device numbered 4202 is
included as a part of Datas et 1. Therefore, the relation established with Dataset 1 is not withdrawn.
