If we grant that kilometer is a property/relation/function between
a distance dimension object and a number, then the choice of
representations would be:

    <River id="Yangtze">
        <length kilometers="6300"/>
    </River>

or alternatively:

    <River id="Yangtze">
        <length>
            <kilometer>6300</kilometer>
        </length>
    </River>

This is quite a radical approach.  I am surprised that there
aren't more comments, since the "conventional wisdom" is
not to treat kilometer as a property/relation/function, but rather
to treat it as the value of a property, e.g.,

  <River id="Yangtze">
       <length unit="kilometer">6300</length>
  </River>

Thoughts?  /Roger
