Does the NetCDF java library version 2.1 support NcML aggregations (i.e.
nested <netcdf> tags and <aggregation> tags)?  The NcML web pages
suggest that it is the reference implementation but I can't find any
reference to aggregation in the javadoc.  I've also tried a couple of
test cases which don't appear to work.

If not, does anyone know of an implementation of NcML aggregations,
whether in java or any other language?
