<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="sqlscripts"
            xmlns="sqlscripts" elementFormDefault="qualified">

    <xsd:element name="root">
      <xsd:complexType>
        <xsd:sequence>
          <xsd:element name="script" type="script_type" maxOccurs="unbounded" />
          <xsd:element name="parameter_type" type="xsd:string" 
                                                                                maxOccurs="unbounded" />

    <xsd:complexType name="script_type">
        <xsd:sequence>
            <xsd:element name="name" type="xsd:string" />
            <xsd:element name="file" type="xsd:string" />                    
            <xsd:element type="parameter_type" maxOccurs="unbounded" />
        </xsd:sequence>
    </xsd:complexType>  

</xsd:schema>

The main problem I am having is I want the element that surrounds the parameter to
be parameter type name. So if the element is USERNAME and the value is pparker then I know that ppparker is a username and not a PAssword or string or whatever. But I have not been able to find how to do this with the xml schema.

I also would like to create the name field as a key or a unique, I have found a few examples of that but nothing that has worked for me. (I am validating the XML with C# validationReader)

Any help would be greatly appreciated.
