+/// @brief The @c D2Zone encapsulates the Zone section in DNS Update message.
+///
+/// This class is used by the @c D2UpdateMessage to encapsulate the Zone section
+/// of the DNS Update message. Class members hold corresponding values of
+/// section's fields: NAME, CLASS. This class does not hold the RTYPE field
+/// value because RTYPE is always equal to SOA for DNS Update message (see
+/// RFC 2136, section 2.3).
+///
+/// Note, that this @c D2Zone class neither exposes functions to decode messages
+/// from wire format nor to encode to wire format. This is not needed, because
+/// @c isc::d2::D2UpdateMessage class uses @c D2Zone only to return the parsed
+/// Zone information to the caller. Internally, D2UpdateMessage parses and
+/// stores Zone section using @c isc::dns::Question class, and the @c toWire
+/// and @c fromWire functions of the @c isc::dns::Question class are used.
