If I remove start/stop/format values, then element will have to store time data
(start/stop if any) related to every UID somewhere in internal structure. And
after receiving TOC select event element will look in that internal structure
(and not in the TOC) to find positions for particalur UID. Is that right?

Well, we can think of it after I'll take care for other stuff :)
