It has always been true that subtitles are NOT verbatim. There are
limitations in the number of characters per second that can be displayed via
any subtitling mechanism - not to mention the issues when multiple speakers
are simultaneously speaking. Part of the art of subtitling (by which I mean
the process of creating subtitles for a program) is to capture the essence
of what is spoken in a succinct form. In captioning there is a greater
tendency towards a verbatim transcript. (SMPTE definitions used).

However these distinctions are IMHO far removed from the requirements of a
TT standard - which should be to define an agnostic mechanism for the timed
delivery of text. Using XML, tags to provide distinction between the text
categories (for want of a better term) should be optional, but undefined by
the standard. The TT standard should IMHO only **define** tags that are
necessary for the temporal control of the display of text.
