Staging Options: Additional tags that help to further describe the document (e.g. document source system, context, category...) and allows it to be found again by browsing and searching.

Tags must follow the kebab case naming convention (lowercase, words separated by hyphens)

Existing tags are retained if no value is defined. Defined values replace the existing tags. To delete all text without creating a tag, an empty tag has to be defined (e.g. &tag=)
