It turns out to be useful in ADDE to have "super" datasets that are composed of
other datasets that are defined.  I assume that this is what you mean by 
datasets
like:

GFS-AKPS     99999    GFS - Alaska/PS; forecast and analysis
GFS-AKPSLRES 99999    GFS - Alaska/PS; low resolution
GFS-AKPSSSIF 99999    GFS - Alaska/PS; analysis - final run
GFS-ALL      99999    GFS - All Global Forecast System grids
GFS-GLME     99999    GFS - Global/Merc; forecast and analysis (thinned)
GFS-GLMELRES 99999    GFS - Global/Merc; low resolution
GFS-GLMENS   99999    GFS - Global/Merc; forecast and analysis (thinned)
GFS-HIME     99999    GFS - Hawaii/Merc; forecast and analysis
GFS-HIMELRES 99999    GFS - Hawaii/Merc; low resolution
GFS-HIMESSIF 99999    GFS - Hawaii/Merc; analysis - final run
GFS-NHPS     99999    GFS - N Hemi/PS; forecast and analysis
GFS-NHPSLRES 99999    GFS - N Hemi/PS; low resolution
GFS-NHPSSSIF 99999    GFS - N Hemi/PS; analysis - final run
GFS-NWME170  99999    GFS - NW Quad/Merc; low resolution (T170)
GFS-NWME62   99999    GFS - NW Quad/Merc; low resolution (T62)
GFS-PRPSLRES 99999    GFS - Puerto Rico/PS; low resolution
GFS-PRPSSSIF 99999    GFS - Puerto Rico/PS; analysis - final run
GFS-USLC     99999    GFS - CONUS/LC
GFS-USPS     99999    GFS - CONUS/PS; forecast and analysis
GFS-USPS2    99999    GFS - CONUS/PS; double resolution
GFS-USPSLRES 99999    GFS - CONUS/PS; low resolution
GFS-USPSSSIF 99999    GFS - CONUS/PS; analysis - final run

The definitions for all of the datasets in the list except GFS-ALL should
be mutually exclusive.  GFS-ALL is the union of all of the other datasets.

Defining a dataset that is the union of other datasets is long used practice
in ADDE.  For instance, the RTPTSRC dataset is composed of:

dsinfo.k P RTPTSRC

        Dataset Names of Type: POINT in Group: RTPTSRC

------------ ------   --------------------------------------
AIRCRAFT        10    Real-Time Aircraft data
GFSMOS          10    Real-Time GFS Model Output Statistics
NAMMOS          10    Real-Time NAM Model Output Statistics
NGMMOS          10    Real-Time NGM MOS data
PROF6MIN        10    Real-Time 6-Minute Profiler data
PROFHOURLY      10    Real-Time Hourly Profiler data
PTSRCS         120    All point data in MDXX files

UPPERSIG        10    Real-Time Upper Air (Significant)

DSINFO -- done

RTPTSRC/PTSRCS is the union of all of the other datasets.  With it, you can get
a quick overview of what elements are accessible in all of the subsets:

Last comment:

The names of the RTGRIBS datasets were specified (chosen) by SSEC.  Since SSEC 
created
the set above first, I decided to adopt it instead of creating a new list for 
Unidata
sites.  It is my hope/desire that every site making model data publically 
available via
ADDE use a standardized set of names for the datasets.

Cheers,

Tom
