/// 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 getText() method.
