Detailed Description

Document interface for format-specific feed documents as parsed from a document source (see DocumentSource).

The Document classes from the several syndication formats must implement this interface. It's main purpose is to provide access for document visitors (see DocumentVisitor). Usually it is not necessary to access the format-specific document at all, use Feed for a format-agnostic interface to all feed documents supported by the library.
