Is there a limit to the size or number of entries that can be placed within the 
values
NcML element?  I'm attempting to get a set of NetCDF files without lon/lat 
variables -
but with x/y variables - to be read as a featureCollection by adding NcML 
entries of the
form:

      <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>

        <variable name="lat_rho" shape="eta_rho xi_rho" type="float">
          <attribute name="units" type="String" value="degrees_north" />
            <values>[671x191 blankspace-separated latitudes here]</values>
        </variable>

The lat and lon variables exist in a separate file and I've extracted them into 
single
strings using ncks which I've stuck between appropriate <values></values> 
locations.

The error messages in featureCollectionScan.log are:
