Hi Dick,

SRT will definitely not be used for that. That's what DFXP would be used for.

I am fully aware that smilText can have that resolution, too. I was
taking it in the context of counting how many characters were used in
the example and SRT is smaller even with a full time code.
Incidentally, real subtitles hardly ever fall on a full second
boundary, so milliseconds are always useful. Also, the simplicity of
having only one fixed time format is mirrored in a simple parsing
implementation - the more formats there are, the more difficult and
error-prone the parsing becomes. SRT avoids this.

meet the needs of all involved. I would be open to swapping out DFXP
and replacing it with smilText, but I believe DFXP is more flexible.
Also, I believe smilText can be transcoded to DFXP without loss of
information - the other direction is not true. That tells me that
smilText is not necessary.

I am sorry if that was your perception - it is not what I said. I have
the highest of respect for the W3C, but I also respect the work of
others out there. I do not take the W3C as a superior organisation
over everyone else - that's all.

Indeed. :-)
