<?xml version="1.0" encoding="UTF-8"?>
<policylist>
  <Policy>free
        <Name>Seagull
            <Bill>0.00</Bill>
        </Name>  
   </Policy>
  <Policy>standard
        <Name>Robin
            <Bill>0.00</Bill>
        </Name>
    </Policy>
  <Policy>premium
        <Name>Crow
            <Bill>0.00</Bill>
        </Name>
  </Policy>
</policylist>
