[Does an XML complext type always have an associated namepace]

[chandru_bn]

Hello,

I am going through a document in which is defined a XML complex type(EventType) for handling events.

But the EventType does not have an associated namespace for it. All other complext types defined in the document have a namespace associated with them. So, I want to know whether is it mandatory to have the namespace associated with the complext type?

The sample schema is given below.

<xs:complexType name="A"> 
<xs:simpleContent> 
<xs:extension base="xs:string"> 
<xs:attribute name="Role" type="xs:string" use="required"/> 
</xs:extension> 
</xs:simpleContent> 
</xs:complexType> 

<xs:complexType name="B"> 
<xs:sequence> 
<xs:element name="Thumbprint" type="ThumbprintType"/> 
</xs:sequence> 
</xs:complexType> 

<xs:complexType> 
<xs:element name="EventType"> 
<xs:sequence> 
<xs:element name="ClientCertificate" type="ClientCertificateType"/> 
</xs:sequence> 
</xs:complexType>

Any help would be great.

thankx & rgds,
