/// @copydoc GlossaryDocument
///
/// For example:
///
/// @verbinclude document1
///
/// All documents contain two special fields, the document handle in @LIT{_id}
/// and the etag aka document revision in @LIT{_rev}.
///
/// @copydoc GlossaryDocumentHandle
///
/// @copydoc GlossaryDocumentIdentifier
///
/// @copydoc GlossaryDocumentRevision
///
/// @copydoc GlossaryDocumentEtag
///
/// The basic operations (create, read, update, delete) for documents are mapped
/// to the standard HTTP methods (POST, GET, PUT, DELETE). An identifier for the
/// document revision is returned in the "ETag" header field. If you modify a
/// document, you can use the "If-Match" field to detect conflicts. The revision
/// of a document can be checking using the HTTP method HEAD.
///
/// @section RestDocumentResource Address and ETag of an Document
/////////////////////////////////////////////////////////////////
///
/// All documents in ArangoDB have a document handle. This handle uniquely
/// defines a document and is managed by ArangoDB. All documents are
/// found under the URI:
///
/// @LIT{http://server:port/_api/document/document-handle}
///
/// For example: Assume that the document handle, which is stored in
/// the @LIT{_id} field of the document, is @LIT{7254820/362549736},
/// then the URL of that document is:
///
/// @LIT{http://localhost:8529/_api/document/7254820/362549736}
///
/// Each document also has a document revision or etag with is returned
/// in the "ETag" header field when requesting a document.
///
/// If you obtain a document using @LIT{GET} and you want to check if a 
/// newer revision is available, then you can use the "If-None-Match"
/// header. If the document is unchanged, a @LIT{HTTP 412} is returned.
///
/// If you want to update or delete a document, then you can use the
/// "If-Match" header. If the document has changed, then the
/// operation is aborted and a @LIT{HTTP 412} is returned.
