- Do we get to review the bundles with LIDs:
  urn:nasa:pds:soho
  urn:nasa:pds:compil-comet
- Did we agree on the mission LID? I thought:
  urn:nasa:pds:context:investigation:mission.solar_and_heliospheric_observatory
We could shorten the end to .soho if desired if every interested party
agrees. In this review, swan_derived/data/*xml have the short while all the
other *.xml have the long.
- We recommend that every label, including for collections and for
documents, have lid_references to investigation, spacecraft, instrument,
and target. Assuming the long investigation LID, the LIDs are:
  urn:nasa:pds:context:investigation:mission.soho
  urn:nasa:pds:context:instrument_host:spacecraft.soho
  urn:nasa:pds:context:instrument:lasco.soho
  urn:nasa:pds:context:instrument:swan.soho
- As usual, EN encourages the addition of
  xmlns:pds="http://pds.nasa.gov/pds4/pds/v1"
to the root tag, as well as using https: for actual PDS URLs.

document/spacecraft_info/*.xml
- Replace the TBDs in the lid_references.

polarimetry/data/dbcp.xml
- Line 82 references:
  urn:nasa:pds:compil-comets:polarimetry:dbcp_references
No product in this delivery has that LID. Since dbcp_references.tab sits
in this directory, it looks like dbcp_references.xml is missing. Or the
lidvid_reference should be removed.

swan_derived/collection.xml
- Lines 90 and 91:
  <lid_reference>urn:nasa:pds:soho:document</lid_reference>
  <reference_type>collection_to_document</reference_type>
Can you refer to a specific document? Referring to an entire collection
would be unprecedented.
- Line 67: typo in lid_reference
  urn:nasa:pds:context:incstrument_host:spacecraft.soho


swan_derived/data/*.xml
- the lid_reference to the spacecraft should change from
  urn:nasa:pds:context:instrument_host.soho
to
  urn:nasa:pds:context:instrument_host:spacecraft.soho
- the lid_reference to the instrument should change from
  urn:nasa:pds:context:instrument.soho.swan
to
  urn:nasa:pds:context:instrument.swan.soho
- we suggest adding a lid_reference to the target in each label. It would
go in Observation_Area/Target_Identification/Internal_Reference.
