Hi Rich, Sorry, my mistake. I didn't catch that these were location attributes in NcML. I tried this in datasetScan@location values and that worked. Though netcdf@location values in aggregations are handled behind the scenes with the same code that handles datasetScan@location values, there must be a layer on top that restricts the location values in aggregations. Yes, John's response is correct, forward slashes will always work in both situations. Sorry for the confusion. Ethan > Below is the actual dataset that failed in TDS4.
