Found a conflict between the documentation and the parser behavior. The org-mode documentation[1] for description list items says that TAG '[...] does not contain the substring " :: "' Using this sample document, I have created a plain list item with a tag that contains that substring by wrapping it in a verbatim block: ``` - =foo :: bar= :: baz ``` Which parses to: ``` (org-data (:standard-properties [1 1 1 23 23 0 nil org-data nil nil nil 3 23 nil #<buffer *scratch*> nil nil nil] :path nil :CATEGORY nil) (section (:standard-properties [1 1 1 23 23 0 nil first-section nil nil nil 1 23 nil #<buffer *scratch*> nil nil #0]) (plain-list (:standard-properties [1 1 1 23 23 0 nil top-comment nil nil nil nil nil nil #<buffer *scratch*> nil ((1 0 "- " nil nil "=foo :: bar=" 23)) #1] :type descriptive) (item (:standard-properties [1 1 19 23 23 0 (:tag) item nil nil nil nil nil nil #<buffer *scratch*> nil ((1 0 "- " nil nil "=foo :: bar=" 23)) #2] :bullet "- " :checkbox nil :counter nil :pre-blank 0 :tag ((verbatim (:standard-properties [3 nil nil nil 15 0 nil nil nil nil nil nil nil nil #<buffer *scratch*> nil nil #3] :value "foo :: bar")))) (paragraph (:standard-properties [19 19 19 23 23 0 nil nil nil nil nil nil nil nil #<buffer *scratch*> nil nil #3]) #("baz\n" 0 4 (:parent #4))))))) ``` It seems that "TAG-TEXT" is not just text but it can include objects and those objects can include the substring " :: ".
