Emacs version: 29.1

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 " :: ".

The following does not address your particular question, it is just a
warning. Be careful with "::" since the following is recognized as a
description list item.
- =foo :: bar=

It is simpler.
Everything after the bullet and before the last " :: " is considered as
tag. Everything after the last " :: " is description.
Then, tag and description are parsed, allowing objects inside.
org-syntax document is inaccurate here - it says that the _first_ " :: "
is used as tag:description delimiter, not the _last_.
I do not see any benefit changing the current parser. So, we probably
need to update org-syntax document instead.

I have not realized that besides
- <shell:echo "a :: b">
that is parsed as 'b">' description, another surprise is
- or :: <shell:echo "c :: d">
where description is 'd">' and the link is truncated.

I've written a patch (attached) with my proposed wording changes to the documentation, should I be starting another thread or does dropping it here work best? I do not have commit access so I'd need someone with such authority to do the last bit.

You can just modify subject with [PATCH], as I did.

Sure.

It does not fully represent what is going on - Org parser is top-down
and does not parse objects before it is done parsing the descriptive
list item. So,
- *foo :: bar* does not actually contain bold markup
Rather it is "* foo" tag + "bar* does not actually contain bold markup" description.
What happens is that the parser splits the first line of the item by the
last " :: " and only then proceeds with parsing the tag and description
using standard set of objects:
- <....> :: <text not containing :: >

Sorry for the delay, I've been busy in the IRLs. I've updated the patch to reflect that the parser grabs the text before the last " :: " and then parses it as objects. The new patch is attached.

Applied, onto master, with minor amendments (fixed "of of").
