ANY FT0 | FT1 | FT2 | ... | FT31 Predefined feed set name for any feed type
NONE - Predefined feed set name for no feed types (will not match anything)
DDPLUS FT0 | FT1 Predefined feed set name for PPS or DDS
WMO FT0 | FT1 | FT2 | FT3 Predefined feed set name for PPS, DDS, HDS, or IDS
UNIDATA FT0 | FT1 | FT2 | FT3 | FT5 Predefined feed set name for PPS, DDS, HDS, IDS, or UNIWISC
FSL FT6 | FT7 | FT8 | FT9 | FT10 Predefined feed set name for PCWS, FSL2, FSL3, FSL4, or FSL5

NOTE: The alternate names for each feed type are simply aliases and can be used interchangably. However, aliases are introduced in LDM versions over time and therefore not all aliases are known by all LDM versions.
