What are the possible element containers

Sections

Sections are divided by headlines.

  Zeroth section
  * First headline
  First section
  ** Child headline
  Child section
  * Second top-level headline
  Second top-level section

Greater blocks

  #+begin_center
  elements
  #+end_center

Drawers

  :drawername:
  elements
  :end:

Dynamic blocks

  * Headline
  #+BEGIN: clocktable :scope subtree :maxlevel 2
  #+CAPTION: Clock summary at [2023-04-16 Sun 16:13]
  | Headline     | Time   |
  |--------------+--------|
  | *Total time* | *0:00* |
  #+END:

Footnote definitions

  [fn:1] A footnote definition.

  [fn:2] A multi-line

  footnote definition.

Plain Lists

  1. foo
     1. bar
  2. baz

Which container takes priority

This test interleaves the opening and closing of each element container to see which element becomes parsed vs gets broken up. The row determines the first opening element and the column determines the second opening element.

	Section	Greater Block	Drawer	Dynamic Block	Footnote Definition	Plain List
Section	-	Section	Section	Section	Section	Section
Greater Block	Section	First	First	First	First	First
Drawer	Section	First	First	First	First	First
Dynamic Block	Section	First	First	First	First	First
Footnote Definition	Section	First	First	First	-	-
Plain List	Section	Second	Second	Second	-	First

Possible solutions

Create tiers of exit matchers

• Document level (sections/headlines)
• Greater Block / Dynamic Block
• Remaining element containers
• Object containers

What if we ignore exit matchers of lower tiers

Test Case 1

  # A plain list containing a greater block that contains a drawer
  1. foo
     #+begin_center
     :drawername:


     :end:
     #+end_center
  2. bar
     :drawername:


     :end:
