Dinesh,

      In test.xsd, instead of writing <xs:element name="Test1_Root"/> you
would write something like <xs:element ref="t1:Test1_Root"
xmlns:t1="test1"/>.

      Although test.xsd is reference an 'element' in test1.xsd, the
mechanics are similar to when a schema references a 'type definition' in a
second schema.  Please read this section of the XML Schema Primer for
information:

Hi,
I have 2 XSDs, test.xsd and test1.xsd

test.xsd

<xs:schema targetNamespace="test" xml:ns="test1"
xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"
attributeFormDefault="unqualified">
             <xs:import namespace="test1" schemaLocation="C:\Documents and
Settings\dsankara\Desktop\Include Test\test1.xsd"/>
             <xs:element name="Test_Root">
                         <xs:annotation>
                                     <xs:documentation>Comment describing
your root
element</xs:documentation>
                         </xs:annotation>
                         <xs:complexType>
                                     <xs:sequence>
                                                 <xs:element name="t1"
type="xs:string"/>
                                                 <xs:element name="t2"
type="xs:string"/>
                                                 <xs:element
name="Test1_Root"/>
                                     </xs:sequence>
                         </xs:complexType>
             </xs:element>
</xs:schema>

test1.xsd
<xs:schema targetNamespace="test1"
xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"
attributeFormDefault="unqualified">
             <xs:element name="Test1_Root">
                         <xs:annotation>
                                     <xs:documentation>Comment describing
your root
element</xs:documentation>
                         </xs:annotation>
                         <xs:complexType>
                                     <xs:sequence>
                                                 <xs:element name="E1"
type="xs:string"/>
                                                 <xs:element name="E2"
type="xs:string"/>
                                     </xs:sequence>
                         </xs:complexType>
             </xs:element>
</xs:schema>

My goal is to import test1.xsd into test.xsd and reference the root element
of test1.xsd so that whenever i add or remove elements in test1.xsd i don't
have to change anything in test.xsd.
For example, if i add another element called "E3" in test1.xsd i should be
able to access it without any code changes in test.xsd.
Is it possible to do it?

Thanks
