One thing about the article that I did not find clarification on was the difference between the flags 1 and 2: in bol it says if 1 used and combined with XML_Elements then attribute centric mapping is applied first and then the element centric mapping applied to those columns not handled while if 2 is used with XML_Attributes then attribute centric mapping is still applied first and then the element centric mapping is applied to the remaining columns not handled. I found this very odd and haven't found an explanation for this oddness- other places have kept repeating that. Can anyone clarify this?
