Swordfish: StorageGroup.StorageGroup schema vs mockup

I am new to redfish and swordfish. In trying to understand the swordfish schema, I was going through the mockups posted on SNIA. The StorageGroup schema points to a volume collection. However, one mockup shows a list of volumes while the other shows a collection of volumes. I presume the latter is correct? See relevant cut pastes below-



/redfish/v1/StorageServices/FileService/Storage/StorageGroups/1 :-



"@odata.context": "/redfish/v1/$metadata#StorageGroup.StorageGroup",



"@odata.id": "/redfish/v1/StorageServices/FileService/Storage/StorageGroups/1",



"@odata.type": "#StorageGroup_1_0_0.StorageGroup",



...



"Volumes": [



{



"@odata.id": "/redfish/v1/StorageServices/FileService/Volumes/61001234876545676100123487654567"



},



{



"@odata.id": "/redfish/v1/StorageServices/FileService/Volumes/65456765456761001234876100123487"



}



],



...







Whereas /redfish/v1/StorageServices/1/StorageGroups/1 shows a volume collection :-

"@odata.context": "/redfish/v1/$metadata#StorageGroup.StorageGroup/1",



"@odata.id": "/redfish/v1/StorageServices/1/StorageGroups/1",



"@odata.type": "#StorageGroup_1_0_0.StorageGroup",



...

"Volumes": {"@odata.id": "/redfish/v1/StorageServices/1/Volumes"},



...
