// This class wraps the captured content and the detached nodes that need to be
// sent out by the ContentCaptureTask, it has a Document to DocumentSession
// mapping, and all data is grouped by document. There are two sources of data:
//
// One is the captured content which is set by the ContentCaptureTask through
// SetCapturedContent() only if the task session is empty, i.e all data must be
// sent before capturing the on-screen content, the captured content is then
// grouped into DocumentSession.
//
// Another is the detached nodes which are set by the ContentCaptureManager,
// they are saved to the DocumentSession directly.
//
// ContentCaptureTask gets the data per document by using
// GetUnsentDocumentSession() and GetNextUnsentNode(), and must send
// all data out before capturing on-screen content again.
