I would suggest you read up on the basics in https://jazz.net/wiki/bin/view/Deployment/RTCProcessFundamentals and then reconsider your question.
The post is so poorly constructed. I believe it is related to this post.

So the answer is:
Use * as the field selection should give you "all" fields. For example, workitem/workItem/(description|summary|severity|state) show you only the select four attributes, while workitem/workItem/* will show you all the attributes.
