 /**

  * A document within KEW.  A document effectively represents a process that moves through

  * the workflow engine.  It is created from a particular {@link DocumentType} and follows

  * the route path defined by that DocumentType.

  *

  * <p>During a document's lifecycle it progresses through a series of statuses, starting

  * with INITIATED and moving to one of the terminal states (such as FINAL, CANCELED, etc).

  * The list of status on a document are defined in the {@link KEWConstants} class and

  * include the constants starting with "ROUTE_HEADER_" and ending with "_CD".

  *

  * <p>Associated with the document is the document content.  The document content is XML

  * which represents the content of that document.  This XML content is typically used

  * to make routing decisions for the document.

  *

  * <p>A document has associated with it a set of {@link ActionRequestValue} object and

  * {@link ActionTakenValue} objects.  Action Requests represent requests for user

  * action (such as Approve, Acknowledge, etc).  Action Takens represent action that

  * users have performed on the document, such as approvals or cancelling of the document.

  *

  * <p>The instantiated route path of a document is defined by it's graph of

  * {@link RouteNodeInstance} objects.  The path starts at the initial node of the document

  * and progresses from there following the next nodes of each node instance.  The current

  * active nodes on the document are defined by the "active" flag on the node instance

  * where are not marked as "complete".
