Would a more compact version like this work?

<TimeSeries type="delta_t">

   <Meta>
     <Param name="first" value="2007-07-01T21:44:00+0000" ucd="time.epoch;" units="iso8601" />

     <Time units="s" uncertainty="0.5" />
     <Flux type="mag" band="R" uncertainty="0.01" />

   </Meta>
   <Data>

     <Row number="1">
       <Time>0</Time>
       <Flux>13.2</Flux>
     </Row>
     <Row number="2">
       <Time>1</Time>
       <Flux>13.3</Flux>
     </Row>
      .
      .
      .

   </Data>
</TimeSeries>

...i.e. set up default Time/Flux metainfo that would apply to all Time/Flux values in the Data section, allowing them to be overridden through explicit values in the Time/Flux sections in Al's quoted example?

(of course, I still don't see why a VOTable wouldn't work, but that was my chief objection at the HTN/VOEvent meeting where The Napkin was wrote upon, blessing us all with The Napkin Representation, but hey... :-) )
