We kept the set of properties that are supported for human tasks (name, actor, priority, etc.) small by default (for simplicity). But it should be straightforward to extend this with additional properties if you want to use more advanced features of the WS-HT service. Take a look at the WSHumanTaskHandler. This contains the logic that translates the work item parameters to invocations of the WS-HT service. You can already assign tasks to users (or a group of users) using the actorId property. I guess you could add start and end date properties there as well (and I assume they map to activation and expiration times in the WS-HT service?). Similarly, a deadlines or escalation property could contain a description that can be translated to escalation elements in the WS-HT service. Feel free to find me on our #drools irc channel (on freenode) if you have more questions. We would be very interested if you would consider contributing features like this back to the project.
