Default set to resource-only since DITA 1.3
The short description (<shortdesc>) element occurs between the topic title and the topic body, as the initial paragraph-like content of a topic, or it can be embedded
in an abstract element. The short description, which represents the purpose or theme of the topic, is also intended to be used as a link preview and for searching. When used within a
DITA map, the short description of the <topicref> can be used to override the short description in the topic. Category: Topic elements
