/// \c rdata::Rdata class, and provides trivial accessors specific to the
/// MINFO RDATA.

    /// \note
    /// Unlike the case of some other RDATA classes (such as
    /// \c NS::getNSName()), this method constructs a new \c Name object
    /// and returns it, instead of returning a reference to a \c Name object
    /// internally maintained in the class (which is a private member).
    /// This is based on the observation that this method will be rarely
    /// used and even when it's used it will not be in a performance context
    /// (for example, a recursive resolver won't need this field in its
    /// resolution process).  By returning a new object we have flexibility
    /// of changing the internal representation without the risk of changing
    /// the interface or method property.
    /// The same note applies to the \c getEmailbox() method.
