I am getting a strange error where it doesn't seem to recognize "paymentProfile(though this is a valid input element as per the specification on the CIM XML API  document) and only wants to see refId and customerProfileID for this particular call. The error is copied below

{'text_': u"The element 'createCustomerPaymentProfileRequest' in namespace 'AnetApi/xml/v1/schema/AnetApiSchema.xsd' has invalid child element 'paymentProfile' in namespace 'AnetApi/xml/v1/schema/AnetApiSchema.xsd'. List of possible elements expected: 'refId, customerProfileId' in namespace 'AnetApi/xml/v1/schema/AnetApiSchema.xsd'."}

I am using a Sandbox Authorize.net login/transaction key. Any suggestions as to why this might be happening(I'm baffled as everything is going through and it should be accepted as a valid input element.
