I've got the following xml, and I'm trying to develop an xsd (below) to 
validate it. For the most part, my xsd is good, except I am having trouble 
accomodating the text after the Completed_By tag.  How can I do this?

<ns0:Assessment xmlns:ns0="http://AIM.xsd">
    <Location>ABC</Location>
    <Client>1234A</Client>
    <Client_Name>FRED SMITH</Client_Name>
    <Address>123 St, City Prov</Address>
    <City>CityName</City>
    <Province>AB</Province>
    <Postal_Code>LNL NLN</Postal_Code>
    <Telephone>555-555-5555</Telephone>
    <System>Assessment</System>
