What is wrong with 

<relation id="1977">
  <tag k="restriction" v="board_only" />
  <member type="node" ref="321" role="" />
</relation>

<relation id="1976">
  <tag k="type" v="route" />
  <tag k="name" v="Oxford Bus 5" />
  <member type="node" ref="123" role="bus_stop" />
  <member type="relation" ref="1977" role="bus_stop" />
</relation>

The problem is that whatever structure is in the XML data has to be
translated into the database schema used by the API. To keep that
simple the XML should be simple, too.
