[thredds] Modifying GRIB collection with NcML

[Jordan Walker <jiwalker@xxxxxxxx>]

I'm working off the tds4.3 documentation for FeatureCollections and at 
the end it describes modifying the component files of the collection 
with NcML.  I would like to do this for a GRIB type of 
FeatureCollection, but I cannot seem to get it to pick up any of my 
modifications.  Is this feature allowed for type GRIB, and if so what am 
I doing wrong?

My catalog looks like so:
<featureCollection name="RFC" featureType="GRIB" harvest="true" 
path="grib/NPVU/RFC">
<collection spec="/home/test/qpe/**/QPE\.#yyyyMMdd#\.009\.1..$"
                olderThan="5 min"/>
<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>
<attribute name="test" value="value" />
</netcdf>
</featureCollection>


And everything works, but test=value does not show up in my global 
attributes.
