[THREDDS #ZUR-765141]: another one that works as NcML, but not as THREDDS Catalog via OpenDAP

Rich,

Your test case was good, the ncml worked and the OCOS_catalog.xml failed. I 
noticed that the ocean_time variable was in a
different location in the catalog, so I moved the whole aggregation block from 
the ncml file into the catalog and there was success. From what I could 
determine, the ocean_time variable was the only difference. I'm a novice ncml 
guy, so I'll have to get some information about ncml to find out what's the 
scoop about variable location.  I'm including the 
OCOS_catalog.xml, the location tag needs to be updated to your directory 
structure.
