 * ID3v1 and ID3v2 tags
     * conversion between ID3v1 and different versions of ID3v2 is possible
-    * mainly for use in MP3 files but can be added to any kind of file
 * Vorbis, Opus and FLAC comments in Ogg streams
     * cover art via "METADATA_BLOCK_PICTURE" is supported
 * Vorbis comments and "METADATA_BLOCK_PICTURE" in raw FLAC streams
 * Matroska/WebM tags and attachments
 
-Further remarks:
-
-* Unsupported file contents (such as unsupported tag formats) are *generally* preserved as-is.
-* Note that APE tags are *not* supported. APE tags in the beginning of a file are strongly
