file: 'data/pluto_albedo_hof22.xml'
--> There is no missing or invalid or not_applicable constant(s) defined.
--> There are no units defined.
--> There is no reference to the source data to produce this product.  This probably should be defined with the data product, but may need to be else where.

file: 'document/pluto_albedo_hof22_pdfa.xml'
--> I would recommend giving a more descriptive <title> than "Manuscript_Preprint" (similar for <document_name> as well) and <description> than "Submitted Manuscript", perhaps the abstract.
--> For the <author_list>, I would highly recommend putting a space before each semi-colon.

file: 'overview.txt'
--> In the last paragraph the paper "Hofgartner et al. (2018)" is mentioned, but no where is it in this file.  I do see it in the overview.xml file.  Is this sufficient?

file: 'overview.xml'
--> The <External_Reference> <reference_text> does not include the Paper's title/name.  It should be added.
