Of course there were "alternative" representations for a <Row />  
suggested which would look something like this


      <Row number="1">
         <Time units="s">
            <Value>0</Value>
            <Uncertainty>0.5</Uncertainty >
         </Time>
         <Flux type="mag" band="R">
            <Value>13.2</Value>
            <Uncertainty>0.01</Uncertainty >
         </Flux>
      </Row>


      <Row number="1">
         <Time units="s" uncertainty="0.5">0/Time>
         <Flux type="mag" band="R" uncertainty="0.01">13.2</Flux>
      </Row>

A simple time series could be represented as follows,

<TimeSeries type="delta_t">
   <Meta>
      <Param name="first" value="2007-07-01T21:44:00+0000"  
ucd="time.epoch;" units="iso8601" />
   </Meta>
   <Data>
      <Row number="1">
         <Time units="s">
            <Value>0</Value>
            <Uncertainty>0.5</Uncertainty >
         </Time>
         <Flux type="mag" band="R">
            <Value>13.2</Value>
            <Uncertainty>0.01</Uncertainty >
         </Flux>
      </Row>
      <Row number="2">
         <Time units="s">
            <Value>35</Value>
            <Uncertainty>0.5</Uncertainty >
         </Time>
         <Flux type="mag" band="R">
            <Value>13.3</Value>
            <Uncertainty>0.01</Uncertainty >
         </Flux>
      </Row>
        .
        .
        .
   </Data>
</TimeSeries>

or alternatively like this,

<TimeSeries type="delta_t">
   <Meta>
      <Param name="first" value="2007-07-01T21:44:00+0000"  
ucd="time.epoch;" units="iso8601" />
   </Meta>
   <Data>
      <Row number="1">
         <Time units="s" uncertainty="0.5">0/Time>
         <Flux type="mag" band="R" uncertainty="0.01">13.2</Flux>
      </Row>
      <Row number="2">
         <Time units="s" uncertainty="0.5">35/Time>
         <Flux type="mag" band="R" uncertainty="0.01">13.3</Flux>
      </Row>
        .
        .
        .
   </Data>
</TimeSeries>
