/**
 * Representation of the EPP transfer response, as defined in RFC3730.
 * Subclasses of this must specify the object to which the command is mapped.
 * Instances of this class provide an interface to access transfer response
 * data for the object identified in a @link TransferCommand .
 * This relies on the instance first being initialised by a suitable EPP
 * transfer response using the method fromXML.  For flexibility, this
 * implementation extracts the data from the response using XPath queries, the
 * expressions for which are defined statically.
