== Ordered and unordered description lists

Asciidoctor PDF supports unordered and ordered description lists.
These are defined as a description list, but displayed as an unordered or ordered description list with the term as a subject.
Only one term is supported.
The subject is shown using the term font style (bold by default).

By default, the subject is arranged as a run-in followed by a subject stop (`:` by default).

[source,asciidoc]
----
[unordered]
alpha:: partially complete and unstable
beta:: feature complete and undergoing testing
----

The subject stop can be customized using the `subject-stop` attribute.

[source,asciidoc]
----
[unordered,subject-stop=)]
alpha:: partially complete and unstable
beta:: feature complete and undergoing testing
----

If the `stack` role is present, the subject is stacked above the description.
In this case, the subject stop is only used if specified explicitly.
