In the template, there is a space that needed to fill up the form and which is the “Extension” line; it means for branching action such as condition causing branching: action or name of sub use case.
In other words, it does have relation to the use case diagram extension or <>, correct??
For example, if in the use case diagram exists an <> picture, that would mean that it should be included in the cockburn’s use case template.
Or, the extension in the template has no relation to the <> Use case diagram??
