Is not possible to handle flat array

This is an example of an incoming payload
```

xxx
yyyy

CustomData
Test 1


NewData
Test 2

user

```

```
...
public partial class IncomingCall
{
...
[DataMember]
public CallData[] callData;
...
}
```

It will work if you add XmlElementAttribute and the complete schema is described without CoreWCF
```
[System.Xml.Serialization.XmlElementAttribute("callData")]
```
