scalaxb requires missing type

Question

I'm trying to use scalaxb to generate a web service from two wsdl files. Here are the files: https://services.pwsdemo.com/WSDL/PwsDemo_creditcardtransactionservice.xml.
https://services.pwsdemo.com/WSDL/PwsDemo_creditcardmanagementservice.xml
I downloaded it to my local machine and ran the following command:
$ scalaxb PwsDemo_creditcardmanagementservice.xml PwsDemo_creditcardtransactionservice.xml -p delta

I got the error:
Referenced type {http://schemas.datacontract.org/2004/07/ThreeDelta.Web.Services.ECLinx.Definitions}ClientCredentials was not found.

I have a ClientCredentials class in my code, it's really simple:

class Halo_3Delta_Request_ClientCredentials
{
    protected $ClientCode;
    protected $UserName;
    protected $Password;

    public function __construct($clientCode, $username, $password)
    {
        $this->ClientCode = $clientCode;
        $this->UserName = $username;
        $this->Password = $password;
    }
}

What would be a good way to provide the missing type?

Update:
I located this type definition already present in the wsdl files:

  <xs:complexType name="ClientCredentials">
    <xs:sequence>
      <xs:element minOccurs="0" name="ClientCode" nillable="true" type="xs:string"/>
      <xs:element minOccurs="0" name="Password" nillable="true" type="xs:string"/>
      <xs:element minOccurs="0" name="UserName" nillable="true" type="xs:string"/>
    </xs:sequence>
  </xs:complexType>

So I guess the question now is how to rearrange those files so they pass validation.

Answer 1

The error is merely in XML structure.
Here are the two files rearranged so that they can be parsed by scalaxb:

PwsDemo_creditcardmanagementservice.xml

PwsDemo_creditcardtransactionservice.xml
