[ID3 Dev] An addition for the Compliance Issues list.

[Dale Preston]

TYER
The 'Year' frame is a numeric string with a year of the recording. This
frames is always four characters long (until the year 10000).


I guess that's the reason there's a list like this.  Reasonable men disagree
on the interpretation of the specification as written. :)

4.2.   Text information frames

   The text information frames are the most important frames, containing
   information like artist, album and more. There may only be one text
   information frame of its kind in an tag. If the textstring is
   followed by a termination ($00 (00)) all the following information
   should be ignored and not be displayed. All text frame identifiers
   begin with "T". Only text frame identifiers begin with "T", with the
   exception of the "TXXX" frame. All the text information frames have
   the following format:

     <Header for 'Text information frame', ID: "T000" - "TZZZ",
     excluding "TXXX" described in 4.2.2.>
     Text encoding                $xx
     Information                  <text string according to encoding>

Hope this helps.
