cap-solutions.co.uk - how does SoapUI get the response?

We have a test suite for some IDOX (formerly CAP solutions I believe) web services in SoapUI, and also generated from the WSDL in C#.

 

One of the tests uses the AddVisitsToInspection service:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
       xmlns:mes="http://www.caps-solutions.co.uk/webservices/connectors/731/servicerequest/messagetypes" 
       xmlns:xit="http://www.caps-solutions.co.uk/schema/uniform/731/xi/xitypes">
   <soapenv:Header/>
   <soapenv:Body>
      <mes:AddVisitsToInspection>
         <!--Optional:-->
         <xit:InspectionIdentifier>18/00716/PCOMP</xit:InspectionIdentifier>
         <!--Optional:-->
         <mes:Visits>
            <!--Zero or more repetitions:-->
            <xit:SubmittedVisit>
               <!--Optional:-->
               <xit:VisitTypeCode>PC</xit:VisitTypeCode>
               <!--Optional:-->
               <xit:ActualDateOfVisit>2018-12-11T13:10:00</xit:ActualDateOfVisit>
               <!--Optional:-->
               <xit:OfficerCode>IPAUL</xit:OfficerCode>
               <!--Optional:-->
               <xit:HoursTaken>1.5</xit:HoursTaken>
               <!--Optional:-->
               <xit:Comments>No treatment required</xit:Comments>
            </xit:SubmittedVisit>
         </mes:Visits>
      </mes:AddVisitsToInspection>
   </soapenv:Body>
</soapenv:Envelope>

This is the response - I've deliberately posted from an example which failed:

 

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body>
      <TransactionReport>
         <TransactionComplete>True</TransactionComplete>
         <TransactionSuccess>False</TransactionSuccess>
         <TransactionMessages>
            <TransactionMessage>
               <MessageType>CAPS.CentralServices.CN.InvalidCnCodeValueException</MessageType>
               <MessageBrief>The code value provided for this field is invalid. ListName: XIVTYPE, CodeValue: PC, CodeCategory:</MessageBrief>
               <MessageDetail>CAPS.CentralServices.CN.InvalidCnCodeValueException: The code value provided for this field is invalid. ListName: XIVTYPE, CodeValue: PC, CodeCategory: 
   at CAPS.CentralServices.CN.CnCodeManager.ValidateCnCodeValueByListName(PersistenceSession session, String strListName, String strCodeValue)
   at CAPS.Modules.XI.XiVisit.ValidateVisitForInsert(PersistenceSession session)
   at CAPS.Modules.XI.XIManager.CreateVisitBase(XiInspection inspection, XiVisit visit)
   at CAPS.Modules.XI.XIManager.AddVisitToInspectionWithoutTransaction(XiInspection inspection, XiVisit visit)
   at CAPS.Modules.XI.XIManager.AddVisitsToInspection(XiInspection inspection, XiVisit[] visits)
   at CAPS.Web.Connectors.ServiceRequest.ServiceRequestConnectorService.AddVisitsToInspection(String InspectionIdentifier, SubmittedVisitType[] Visits)</MessageDetail>
            </TransactionMessage>
         </TransactionMessages>
      </TransactionReport>
   </soap:Body>
</soap:Envelope>

 

However I can find no trace of TransactionReport or 

http://www.caps-solutions.co.uk/webservices/connectors/731/servicerequest/messagetypes

in the WSDL response:

      <s:element name="AddVisitsToInspection">
        <s:complexType>
          <s:sequence>
            <s:element minOccurs="0" maxOccurs="1" ref="s9:InspectionIdentifier" />
            <s:element minOccurs="0" maxOccurs="1" name="Visits" type="s9:ArrayOfSubmittedVisitType" />
          </s:sequence>
        </s:complexType>
      </s:element>

      <s:element name="AddVisitsToInspectionResponse">
        <s:complexType />
      </s:element>

Nor is it in the generated C# code which does mention the messagetypes namespace :

    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.CodeDom.Compiler.GeneratedCodeAttribute("dotnet-svcutil", "1.0.0.0")]
    [System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]
    [System.ServiceModel.MessageContractAttribute(
        WrapperName="AddVisitsToInspectionResponse", 
        WrapperNamespace="http://www.caps-solutions.co.uk/webservices/connectors/731/servicerequest/message" +
            "types", IsWrapped=true)]
    public partial class AddVisitsToInspectionResponse
    {
        
        public AddVisitsToInspectionResponse()
        {
        }
    }

So we are mystified as to how SoapUI does this.  Can anyone shed a light?  

What we want is TransactionReport to come back into the C# code, can see no way of doing this at present.
