+ * To identify with which method a frame has been encrypted the encryption

+ *
+ * The owner identifier a URL containing an email address, or a link to a
+ * location where an email address can be found, that belongs to the
+ * organisation responsible for this specific encryption method. Questions
+ * regarding the encryption method should be sent to the indicated email

+ *
+ * The method symbol contains a value that is associated with this method
+ * throughout the whole tag, in the range $80-F0. All other values are reserved.
+ * The method symbol may optionally be followed by encryption specific data.
+ *
+ * There may be several ENCR frames in a tag but only one containing the same
+ * symbol and only one containing the same owner identifier. The method must be
+ * used somewhere in the tag. See {@link ID3_Frame#ENCRYPTION} for more
+ * information.
