Overview

Configuration object for a scan template.

The constructor is designed to take a valid XML representation of a scan template. If you wish to create a new scan template from scratch, use the #load method without a template ID. If you wish to copy and modify an existing template, use the #copy method.

This class is only a partial representation of some of the features available for configuration.
