Extending XML Schemas

Hello,

I have been working on XML Schema.I want to extend schemas with namespaces and parse schemas to decompose the elements of schema.

For example;

I have an XML Schema like this:

?xml version="1.0" encoding="utf-8" ?>


<xs:schema id="BIDM_VB" targetNamespace="http://tempuri.org/BIDM_VB.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/BIDM_VB.xsd" xmlns:mstns="http://tempuri.org/BIDM_VB.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:BIDM="http://tempuri.org/BIDM.xsd" xmlns:VB="http://tempuri.org/VB.xsd">


 <xs:element name="IProject" type="VB:Project" />
</xs:schema>

There is no error in this code but I want to identify the "IProject" element whose type is another element of XML schema (VB). 

How can I do?

Thanks,

Fatma.
