The FormatHooks element defines custom JavaScript functions to run before, during, and after formatting. Its child elements provide the file definition.
Custom functions provide extra control over the formatting process. For example, they can set properties not supported by the configuration file or other job-specific parameters. A JavaScript object will be passed into each function to allow properties that were set in FormatStart to be seen in, for example, FormatPass or FormatEnd. JavaScript can be either embedded in a CDATA block inside the element, or provided in an external file.
