Get vDC Storage Policy quota

Hello.

I want to retrieve the storage policies quota assigned to an Org vDC using PowerCLI.

I initially tried to retrieve this information using $orgvDC.StorageLimitGB but this gives me the sum of the storage profiles quotas (I want the information per storage profile).

I managed to retrieve the vDC's storage profiles this way:

foreach ($vDCStorageProfilein$orgvDC.ExtensionData.VdcStorageProfiles) {

  }

I assume it is possible as there is a "limit" element in the API documentation but I can't find how to retrieve this limit for each storage profile.

Any idea?
