Comment (by yknivag):
http://id3.org/id3v2-chapters-1.0
Section 4.2 states
"It is permitted to include "CHAP" frames that are not referenced by any
"CTOC" frames. For example, these might be used to provide images that can
be presented in synchronisation with the audio, rather than to support a
table of contents."
The corollary of that statement is that all "normal" (non-special) `CHAP`
frames ought to be included in at least one `CTOC` frame.
Excepting the special frames defined in that note, there is no point
having chapters if there is no table of contents and the chapters are,
therefore, not navigable.
