TS-0004: Missing specification for Pollingchannel.requestAggregation
In TS-0004, V4.0.0 the CR "ARC-2017-0395R03-requestAggregationForPollingChannel-R4" was integrated to add the requestAggregation attribute to the PollingChannel resource type. However, there doesn't seem to be a corresponding CR for TS-0004 (ARC-2017-0395 only contains text for TS-0001) and this attribute is missing in the clauses of section 7.4.21 of TS-0004.
