deca SI prefix is missing from the list of units.

Units for "space" axes: angstrom, attometer, centimeter, decimeter, exameter, femtometer, foot, gigameter, hectometer, inch, kilometer, megameter, meter, micrometer, mile, millimeter, nanometer, parsec, petameter, picometer, terameter, yard, yoctometer, yottameter, zeptometer, zettameter

Units for "time" axes: attosecond, centisecond, day, decisecond, exasecond, femtosecond, gigasecond, hectosecond, hour, kilosecond, megasecond, microsecond, millisecond, minute, nanosecond, petasecond, picosecond, second, terasecond, yoctosecond, yottasecond, zeptosecond, zettasecond

The "deca" prefix is missing in this list of units. A "decameter" is 10 meters. A "decasecond" is 10 seconds.

1e-24  yoctosecond
1e-21  zeptosecond
1e-18 attosecond
1e-15  femtosecond
1e-12  picosecond
1e-09  nanosecond
1e-06  microsecond
1e-03  millisecond
1e-02  centisecond
1e-01  decisecond
1e+00  second
1e+01  decasecond
1e+02  hectosecond
1e+03  kilosecond
1e+06  megasecond
1e+09  gigasecond
1e+12  terasecond
1e+15  petasecond
1e+18  exasecond
1e+21  zettasecond
1e+24  yottasecond

Start by locating the NGFF specification sections containing the listed units for space and time axes. Add decameter and decasecond in the appropriate SI-prefix order, then verify that both unit lists and their examples are consistent.
