I double checked, the data was published via GeoServer. But, is there anything that I can doon my end, when I bring it into Arc, using the Data Interoperability extension to get rid of the duplicate ".xsi_nil" fields, or to populate them? Or is this something that has to be corrected on the GeoServer publishing side?
Also, does any one know what ".xsi_nil" means or is used for? THANKSSSSSSS!
