A flag indicating whether this work item has been completed or not. This property is only set by the WorkSession to which this WorkItem belongs.

The template associated with this work item. For interview work items, this is the template that delivers the interview. For document work items, this is the template that generates the document. A single template can be (and often is) associated with both an interview work item and a document work item.

The title of the work item. This is used by a host application when presenting user interface showing the completed and pending work items. Right now each work item maintains its own title internally, but eventually the title could be derived from elsewhere (for example, the Title property of InterviewOptions, or if that's not set then the title associated with a template).

A list of variable names for which no answer was present during assembly of the document. Before an assembly has occurred, this property will be null. After an assembly is complete, this property will be an array of strings. Each string is the name of a variable for which an answer was called for during assembly (either to merge into the document, or in the evaluation of some other expression or rule encountered during assembly), but for which no answer was present in the AnswerCollection.
