[pradhan....@gmail.com]

Hi,

1.I need to compare the element references present within element. like 

<xs:element name="Application">

        <xs:complexType>

            <xs:sequence>

                <xs:element ref="CreditRequest" minOccurs="0"/>

                <xs:element ref="analysisRequest" minOccurs="0" maxOccurs="unbounded"/>

           </xs:sequence>

       </xs:complexType>

</xs:element>

Can you please advise how to achieve the same.

2. How to use SequenceDiffGenerator and what is the "Ctx" needs to be passed.
