well, I agree. It's not clear whether in the transition to P5 we bungled
the definition of @absolute by making it data.temporal, or whether
there was a use case for the "point in real time" notation. Looking
does not help much. The example at
<when id="w0" absolute="sometime Monday morning before Christmas"/>
sort of implies real time, but in a weird way. P5's
<when xml:id="w0" absolute="11:30:00"/>
is a bit clearer, though its not obvious why it helps
to know the time of day but not the date.
I suspect someone once had a pretty clear idea
of how <timeline> was going to be used, but I wonder
whether successive scribes have not mangled the original :-}
The radical may say "Since SMIL now exists, why doesn't
the TEI defer to that and abandon its odd timeline markup".
But that's for another day.
