*/*.lblx
- Most have
  <?xml-model href="https://pds.nasa.gov/pds4/img/v1/PDS4_IMG_1J00_1900.sch"
    ...
    https://pds.nasa.gov/pds4/img/v1/PDS4_IMG_1J00_1900.xsd"
but that version doesn't exist. Probably replace those with
  PDS4_IMG_1J00_1890
- Suggestion: to match the context product's Instrument/name, change
  <name>PEPSSI</name>
to
  <name>PLUTO ENERGETIC PARTICLE SPECTROMETER SCIENCE INVESTIGATION</name>

calibration_files/collection.lblx
- Suggestion: to match the context product's Instrument_Host/name, change
  <name>New Horizons Spacecraft</name>
to
  <name>NEW HORIZONS</name>

calibration_files/collection_inventory.csv
- This file includes
  P,urn:nasa:pds:nh_pepssi:calibration_files:overview::1.0
but the version in the given overview.lblx is 2.0. If this is the first
version given to PDS, please use 1.0.

kem*/*.lblx
- Besides PDS4_IMG_1J00_1900, these have
  <?xml-model href="https://pds.nasa.gov/pds4/sp/v1/PDS4_SP_1J00_1320.sch"
    ...
    https://pds.nasa.gov/pds4/sp/v1/PDS4_SP_1J00_1320.xsd"
but that version doesn't exist. These need _1320 because they have:
  <sp:Bin_Description>
    <sp:bin_profile_description>...
    <sp:Axis_Bin_Set_Energy>...
which is incorrect in _1311. The first available SP dictionary with 1320 is
  PDS4_SP_1M00_1320
- Suggestion: to match the context product's Instrument_Host/name, change
  <name>New Horizons Spacecraft</name>
to
  <name>NEW HORIZONS</name>
- Suggestion: to match the context product's Target/name, change
  <name>Particles</name>
to
  <name>INTERSTELLAR PARTICLES</name>

kem*/collection.lblx
- The only lid_reference to a target that each has is
  urn:nasa:pds:context:target:calibration_field.space or
  urn:nasa:pds:context:target:trans-neptunian_object.486958_2014_mu69
but no product label has either. Also, collection.xml should have a union
of lid_references in its children, i.e.
  urn:nasa:pds:context:target:dust.interstellar_particles
