I am using THREDDS 3.6, and like Bjørge Solli, I have been trying out the 
example aggregation code.  When I initialize the catalog, I get no errors or 
warning in the catalog error file (with addition of dataType="Grid" to the 
dataset element).

I am then able to select the "WEST-CONUS_4km Aggregation" dataset.  However, 
when I select the Access: OPENDAP link, I get the error:

Error { code = 1; message = "No data root for 
dodsC/satellite/3.9/WEST-CONUS_4km"; };

In one of many attempted workarounds, I tried putting the ncml into its own 
file so I could access it through an <access> element.  However, it appears 
that the <access> element ignores the dataFomat="NcML" attribute and tries to 
open the ncml as a netcdf and throws an error.

If anyone has an example xml that uses netcdf aggregation elements please let 
me know... I really need this to work!

BTW, my xml is:
