sample/tour/proc.rb in the Amrita distribution does what you want, setting
element attributes explicitly. See section entitled "proc" at:
http://www.brain-tokyo.jp/research/amrita/rdocs/files/docs/Tour.html

sample/hello/conditional.rb shows another way to achieve different HTML for
odd/even rows, although in this case you'll probably end up with an extra
<div> around each table row. It relies on the fact that if a particular id
is missing (or points to nil or false) it is removed.

<table>
 <div id="links">
  <tr id="odd" class="odd">
    <td><a id="lang"></a></td>
  </tr>
  <tr id="even" class="even">
    <td><a id="lang"></a></td>
  </tr>
 </div>
</table>

links = [
  { :odd=> {:lang=>a(:href=>'http://www.ruby-lang.org') {"ruby"}   } },
  { :even=>{:lang=>a(:href=>'http://www.python.org')    {"python"} } },
  { :odd=> {:lang=>a(:href=>'http://www.perl.org')      {"perl"}   } },
]
