XML Schema for a .NET type that inherits and implements
- by John Ruiz
Hi,
Please consider the following three .NET types: I have an interface, an abstract class, and a concrete class. My question is how to write the XML Schema to include the properties from the interface and from the abstract class.
public interface IStartable
{
bool RequiresKey { get; set; }
void Start(object key);
}
public abstract class Vehicle
{
uint WheelCount { get; set; }
}
public class Car : Vehicle, IStartable
{
public bool RequiresKey { get; set; }
public string Make { get; set; }
publilc string Model { get; set; }
public Car() {}
public void Start(object key)
{
// start car with key
}
}
I don't know how to complete this schema:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="cars"
xmlns="cars"
xmlns:c="cars">
<!-- How do I get car to have vehicle's wheelcount
AND IStartable's RequiresKey? -->
<xs:element name="Car" type="c:Car" />
<xs:complexType name="Car">
<xs:complexContent>
<xs:extension base="c:Vehicle">
<xs:group ref=c:CarGroup" />
</xs:extension>
</xs:complexContent>
</xs:complexType>
<xs:group name="CarGroup">
<xs:sequence>
<xs:element name="Make" type="xs:token" />
<xs:element name="Model" type="xs:token" />
</xs:sequence>
</xs:group>
<xs:complexType name="Vehicle">
<xs:sequence>
<xs:element name="WheelCount" type="xs:unsignedInt" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="IStartable">
<xs:sequence>
<xs:element name="RequiresKey" type="xs:boolean" />
</xs:sequence>
</xs:complexType>
</xs:schema>
