HI,

How to compare element reference 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"/>
