/**
 * <p>Extension for the EPP Domain Create response, representing the Block Create Block extension.</p>
 *
 * <p>Use this to access create data for a domain block as provided in an EPP Domain Create response compliant
 * with RFC5730 and RFC5731. Such a service element is sent by a compliant EPP server in response to a valid
 * Domain Create command with the Block extension.</p>
 *
 * <p>For flexibility, this implementation extracts the data from the response using XPath queries, the expressions
 * for which are defined statically.</p>
