On a specific Web Service, there is a requirement to return an error formatted within a specific XML layout. So, if my assumption is ok, I understand that instead of calling COMRETURNERROR(), I have to lay out the error in something like this:

<Faults>
 <Fault ...>
  <faultcode />
  <faultstring/>
  <detail>
   <faultCode>...</faultCode>
   <faultAction>...</faultAction>
   <faultActor>...</faultActor>
   <faultDetail>...</faultDetail>
  </detail>
 </Fault>
</Faults>

So, if my understand is correct, instead of invoking COMRETURNERROR(), which would have fired a messagebox on the client side, I am returning this XML string such as if everything went fine. It would then be a responsability of the client to detect such situation.

Am I assuming correctly?
