task Tag Rules for Nesting Tasks
When working with the Info*Engine task tag, the following rules apply:
You can nest any number of tasks within another task, and nested tasks can contain other nested tasks.
The task file being referenced can also contain any of the task webjects and any of the custom tags that are available to tasks.
You should always provide exception processing within your task to catch errors when nested tasks fail.
The syntax and complete description of the task tag is described in task Tag.
