  44  * Interface of XML encryption template
  45  *
  46  * <p>This interface represents a encryption template, which is the same as the
  47  * desired xml encryption element[ EncryptedType ] but some of the nodes may be
  48  * empty. The empty entities include CipherValue, which is a subset of
  49  * EncryptedData or EncryptedKey. Empty entities are not allowed in a encryption
  50  * template when performing decryption.</p>
  51  *
  52  * <p>In some cases, the encrypter or decrypter can dertermine and locate the
  53  * EncrytedKey from the encryption template by dereference the RetrievalMethod
  54  * inside EncryptedData.</p>
  55  *
  56  * <p>In some cases, the EncryptedKey need to be clearly pointed out by the
  57  * encryption template.</p>
  58  *
  59  * <p>With the help of encryption context, the encrypter or decrypter specifies
  60  * the key from the KeyInfo in the encryption template.</p>
  61  *
  62  *
  63  * <p>It isn't a good method to set the EncryptedKey here. In general, there is
  64  * a RetrievalMethod in EncryptedData by which we can get the EncryptedKey.
  65  *
  66  * And some times, in the low level, it is hard to determine what the key is
  67  * except that the high level application tell the mechanism and parameters.
  68  *
  69  * So I think it will be more simple that the application set the encrypted key
  70  * information. In this case, the application only need to know the xml schema
  71  * or DTD and the encryption device. If so, the high level application takes the
  72  * action of build the EncryptedKey template and references it in the element of
  73  * EncryptedData. And in this case, the calling to set up EncryptedKey template
  74  * and target is not necessary, because the encrypter or decrypter can determine
  75  * and locate the EncrypedKet from the encryption template of EncryptedData by
  76  * dereference the RetrievalMethod.
  77  *
  78  * In some situation, the high level applications do not want to know anything
  79  * about crypto devices( May be he must, because the lower level do not know
  80  * what the key is ). If it gives the key value, it can get EncryptedKey by
  81  * setting the key template and key value target.</p>
