I want to add the property honorifiqueSuffix to the authors of an article.
Since the author is not a group in terms of schema_metatag definitions, I can not add the field, as indicated via schema_article_example module.
How can I add the property as a "subkey" of the article_author "field".
I do not want to patch on the SchemaPersonOrgTrait or SchemaPersonOrgBase to get this property in the schema metadata.
This should be feasible via a custom tag, as in the sample module.
