* `parameters` - A JSON or XML document defining parameters for the Task.
* `options` - a JSON object defining certain options for this Task. Typically used to provide scope for extensions to the Task Engine.
* `run_later` - if provided, the Task will be scheduled to run at the specified date/time. ex. "7/4/1776 15:30"
