I am not sure what you mean by 'clienterror' or 'servererror' in this 
case because we still don't have a complete mapping of how you think all 
of the old result codes will translate into new.  I would expect that 
this is the next step (we can talk about this on the thursday call).

Maybe I wasn't clear enough on my question.  From the examples that I am 
reading for 'query_exception' it covers several cases:

  - Structure of the message may be wrong, e.g. "no data trigger", "no 
subject element in metadata id=[...]"
  - Content in XML is unexpected, e.g. "eventType [...] in metadata id= 
[...] is not supported"
  - Content is 'wrong' (not sure how to interpret this, maybe its 
unexpected or maybe it is just incorrect vs. what is stored in the 
backend?), e.g. "wrong ipAddress", "wrong hostName"

I would call these things different error messages since they cover 
slightly different cases.

My original question was do you or Roman envision these translating 
directly to a single result code in the new model, or would these be 
encoded as different codes for different situations.

Thanks;
