Following is the synapse configuration.

<definitions xmlns="http://ws.apache.org/ns/synapse">

    <sequence name="main">
        <in>
            <validate>
                <schema key="validate_schema"/>
                <on-fail>
                    <log level="custom">
                       <property name="MSG" value="ON FAIL"/>
                    </log>
                    <send/> 
                </on-fail>
            </validate>
        </in>
        <send/>
    </sequence>

    <localEntry key="validate_schema">
        <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
                   xmlns="http://services.samples" elementFormDefault="qualified"
                   attributeFormDefault="unqualified" targetNamespace="http://services.samples">
            <xs:element name="getQuote">
                <xs:complexType>
                    <xs:sequence>
                        <xs:element name="request">
                            <xs:complexType>
                                <xs:sequence>
                                    <xs:element name="stocksymbol" type="xs:string"/>
                                </xs:sequence>
                            </xs:complexType>
                        </xs:element>
                    </xs:sequence>
                </xs:complexType>
            </xs:element>
        </xs:schema>
    </localEntry>

</definitions>

So isContentAware should be set to true in Validate Mediator.
