The CREDIT_LIABILITY array (a subproperty of CREDIT_RESPONSE) contains a set of objects that represent the loans, obligations, and other financial liabilities that appear on a customer's credit report. Within each object, you'll find a set of properties that provide basic information about the liability:

@_AccountOwnershipType describes the borrower's relationship to the liability: solely responsible, jointly responsible, and so on. The @_AccountOwnershipType property also appears in the objects in the CREDIT_PUBLIC_RECORD array.
@_AccountType describes the general nature of the liability -- credit line, installment, mortgage, open, revolving).
@_AccountStatusType declares the liability's status as of @_AccountStatusDate.

As an example, here we see that the borrower is the sole owner of a revolving account that was open as of September 1, 2021:

"CREDIT_LIABILITY": [
  {
    "@CreditLiabilityID": "TRADE001",
    "@BorrowerID": "Borrower01",
    "@_AccountOwnershipType": "Individual",
    "@_AccountType": "Revolving",
    "@_AccountStatusType": "Open",
    "@_AccountStatusDate": "2021-09-01",
    ...
