# Test Case Document #

## broken_link_or_image ##

This [line][] contains exactly 1 [broken](b r o k e n) \[link\]\(link\), and
this line has 0 `[broken](l i n k s)`.

  [line]: https://localhost/line

The following lines of text contain 0 because they are code blocks:

 ~~~
 There are no [broken](definitely not broken) links here...
 ~~~

   ```
  And there are no [broken](totally not broken) links here.
   ```

    There are also no [broken](nope still not broken) links here!

## empty_list_entry ##

The following list includes an empty item:

1. One
2.
3. Three

## heading_discontinuity ##

When adding a heading, the level of the new heading should be less than or
equal to the previous heading, or the new level should be exactly 1 greater:

> ### Good Heading ###
>
> ### Another Good Heading ###
>
> ##### Bad Heading; (5 - 3) ≠ 1 #####

The level of the first heading in a container sets the floor for all of the
following heading:

> #### First Heading In Block Quote ####
>
> #### Second Heading ####
>
> ### Bad Heading; Level 3 < Level 4 ###
