[tei-council] <timeline> without timing information?

[Martin Holmes]

Take a look at this block from Chapter 8:

--------------------
Where the whole of one or another utterance is to be synchronized, the 
start and end attributes may be used:

<u who="#tom">I used to smoke <anchor xml:id="TS-p10"/> a lot more than this
<anchor xml:id="TS-p20"/>but I never inhaled the smoke</u>
<u start="#TS-p10" end="#TS-p20" who="#bob">You used to smoke</u>

[...]

If synchronization with specific timing information is required, a 
timeline must be included:

<timeline origin="#TS-t01">
  <when xml:id="TS-t01"/>
  <when xml:id="TS-t02"/>
</timeline>
<u who="#tom">I used to smoke
<anchor synch="#TS-t01"/>a lot more than this
<anchor synch="#TS-t02"/>but I never inhaled the smoke</u>
<u who="#bob">
  <anchor synch="#TS-t01"/>You used to smoke<anchor synch="#TS-t02"/>
</u>
-----------------

The expanded version with <timeline> is introduced explicitly to show 
"specific timing information", but it doesn't seem to do so; there's no 
@absolute or @interval, and as far as I can see, the addition of 
<timeline> provides no benefit to the encoding. I think this is a simple 
omission, which could be remedied by adding appropriate timing info, 
like this:


<timeline origin="#TS-t01" unit="s">
  <when xml:id="TS-t01" absolute="15:33:01Z"/>
  <when xml:id="TS-t02" interval="2.5" since="#TS-t01"/>
</timeline>
<u who="#tom">I used to smoke
<anchor synch="#TS-t01"/>a lot more than this
<anchor synch="#TS-t02"/>but I never inhaled the smoke</u>
<u who="#bob">
  <anchor synch="#TS-t01"/>You used to smoke<anchor synch="#TS-t02"/>
</u>

Have I misunderstood, or should I go ahead and make this change?

Cheers,
Martin
