pubmed_230101.dtd: IndexingMethod attribute

Introduced with the 2017 DTD, IndexingMethod specifies the method used to assign Medical Subject Headings (MeSH) to the citation. The valid values for IndexingMethod are:

• Curated - MeSH indexing is provided algorithmically and a human reviewed (and possibly modified) the algorithm results
• Automated - MeSH indexing is provided algorithmically

IndexingMethod is an implied attribute, meaning that it will only be present if a value is specified. If the IndexingMethod attribute is not present, the indexing method is fully human indexed.

For more information, see the technical bulletin, Incorporating Values for Indexing Method in MEDLINE/PubMed XML.
