The Short Description field is an unedited text field available on most record forms. Developers can enter a brief text description that helps them recognize the object when it is later presented on a list.

In several cases, the Short Description text is visible to application users as well as to developers. For these cases, it is important to choose wording of the text to be meaningful to users in the context of their work. For example, Short Description text:
When an application is localized to support users with multiple languages or locales, the Short Description text that is visible to users can be converted through field value rules to a locale-specific equivalent.
The standard activity @baseclass.StandardValidate requires that property pyLabel have a non-blank value.
