Hi..
I am getting error in libxml2 as well as altova spy saying that 
 
"An all modelgroup is neither allowed in complexType definition
"tns:BaseType" nor in its extension tns: DerivedType". "
 
Can you please lookinto this schema whether it is valid or not.

It looks OK to me by visual inspection - I haven't tried running it.
 
Why do you doubt that it's OK?

Hi All,
 
I have one doubt reg. <all> model group extension.
 
i have the following schema. 
 
<schema targetNamespace="testschema" xmlns:tns="testschema">
    <complexType name="BaseType">
        <all>
            <element name="a1" type="string"/>

            <element name="a2" type="string"/>
        </all>
    </complexType>
 
    <complexType name="DerivedType">
        <complexContent>
          <extension base="tns:BaseType">
            <all>
                <element name="a3" type="string"/>
            </all>
        <extension>
        </complexContent>
    <complexType>
 
</schema>
