Here's a sample SOAP request using the doc/lit form of the web service (in this case captured from the JibxSoap version of the application, with indenting enabled):

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
  <SOAP:Body>
    <qk:query xmlns:qk="http://www.sosnoski.com/quakes">
      <qk:min-date>2001-07-25T19:58:24.918</qk:min-date>
      <qk:max-date>2001-09-01T16:00:59.4</qk:max-date>
      <qk:min-long>134.90671</qk:min-long>
      <qk:max-long>178.3323</qk:max-long>
      <qk:min-lat>-47.337864</qk:min-lat>
      <qk:max-lat>-18.00817</qk:max-lat>
    </qk:query>
  </SOAP:Body>
</SOAP:Envelope>

Here's the corresponding SOAP response:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

  <SOAP:Body>
    <qk:results xmlns:qk="http://www.sosnoski.com/quakes" count="1">
