Description List

[ghost]

if you put this markdown:

one two
: three four five six

it gives you the expected output with kramdown:

<dl>
  <dt>one two</dt>
  <dd>three four five six</dd>
</dl>

but not with cmark:

<p>one two
: three four five six</p>

this is because kramdown supports Description Lists:

https://kramdown.gettalong.org/syntax#definition-lists

while cmark only supports it as HTML block:

https://spec.commonmark.org/0.28#html-blocks
