TP needs to be updated, then TC implementation. Current Test Objective says:
"Check that the IUT responds with error when the newly created results in that the field value of attribute currentNrOfInstances exceeds the field value of maxNrOfInstances in the parent container resource".
Following TS-0001 Release 1 (v1.16.0), in section 10.2.19.2:
"If the newly created resource violates any of the policies defined in the parent resource (e.g. maxNrOfInstances or maxByteSize), then the oldest resources shall be removed from the to enable the creation of the new resource"
So, new Test Objective shall be set to:
"Checks that the IUT accepts a newly created contentInstance when the currentNrOfInstances exceeds the field value set in maxNrOfInstances in the parent container resource by removing enough of the oldest resources to allow the creation of the new resource".
