title	Additional keys

Please note that additional keys are often necessary in addition to the base parameter definition below. For example for:

statistical processing (e.g. time interval of processing)
level information (e.g. a given pressure level, say 300 hPa)

Any entry with localTablesVersion=1 should not be used in production outside ECMWF.
