A very useful feature of Sub Station Alpha subtitle format was the
possibility to declare a certain subtitle as comment.
In this way the subtitle is not visualized during playback but is
editable exactly as a dialogue subtitle.
This kind of subtitle events comes very useful for storing
translator/typesetter comments to the other people who'll work on the
script; They are also useful for making a local backup copy of the
subtitle when you test new feature for that subtitle and you probably
want to come back to the original for or leave the original form in the
script for a latter analisys/documentaion.
Proposal:
<subtitle +-subtitle (1..N) start="hh:mm:ss.mmm" @-start (1) stop="hh:mm:ss.mmm" @-stop (0..1) duration="hh:mm:ss.mmm"> @-duration (0..1) <text></text> +-text (0..N) <comment></comment> +-comment (0..N) <image></image> +-image (0..N) <karaoke></karaoke> +-karaoke (0..N) <shape/> +-shape (0..N) ... </subtitle>
Any comment/suggestion is welcome. No replies means "go on" (unmei?).
