Sequential is a container task - it can contain other Ant tasks. The nested tasks are simply executed in sequence. Sequential's primary use is to support the sequential execution of a subset of tasks within the Parallel Task 

The sequential task has no attributes and does not support any nested
elements apart from Ant tasks. Any valid Ant task may be embedded within the
sequential task.
