+/**
+ * The <i>Unique File Identifier frame</i>'s purpose is to be able to identify
+ * the audio file in a database, that may provide more information relevant to
+ * the content. Since standardisation of such a database is beyond this document,
+ * all UFID frames begin with an 'owner identifier' field. It is a null-
+ * terminated string with a URL [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 database implementation.
+ * Questions regarding the database should be sent to the indicated email
+ * address. The URL should not be used for the actual database queries. The
+ * string "http://www.id3.org/dummy/ufid.html" should be used for tests. The
+ * 'Owner identifier' must be non-empty (more than just a termination). The
+ * 'Owner identifier' is then followed by the actual identifier, which may be
+ * up to 64 bytes. There may be more than one "UFID" frame in a tag, but only
+ * one with the same 'Owner identifier'.
