/**
 * @brief Interface definition for the EncryptedKey object
 *
 * The \<EncryptedKey\> element is an abstract type which builds
 * on the EncryptedType element for encrypted data (as opposed to
 * encrypted data).
 *
 * In general, this class should not be used directly.  For most
 * applications, callers will want to use the XENCCipher class
 * instead.
 *
 * The schema definition for EncryptedKey is as follows:
 *
 * \verbatim
  <element name='EncryptedKey' type='xenc:EncryptedKeyType'/>
  <complexType name='EncryptedKeyType'>
    <complexContent>
      <extension base='xenc:EncryptedType'>
        <sequence>
          <element ref='xenc:ReferenceList' minOccurs='0'/>
          <element name='CarriedKeyName' type='string' minOccurs='0'/>
        </sequence>
        <attribute name='Recipient' type='string' use='optional'/>
