Is it possible to use a xsd schema against an xml file that validates the xml file in the following ways:

1. if Attibute1 value is "XYZ" then Attibute2 value should be "ABC"?
if Attibute1 value is "WXYZ" then Attibute2 value should be "DEF"?

current xsd sample:

XML

<xs:attribute name="Attribute1" use="required" form="unqualified" >
            <xs:simpleType>
                <xs:restriction base="xs:string">
                    <xs:enumeration value="XYZ" />
                    <xs:enumeration value="WXYZ" />
                </xs:restriction>
            </xs:simpleType>
        </xs:attribute>

        <xs:attribute name="Attribute2" use="required" form="unqualified" >
            <xs:simpleType>
                <xs:restriction base="xs:string">
                    <xs:enumeration value="ABC" />
                    <xs:enumeration value="DEF" />
                    <xs:enumeration value="GHI" />
                </xs:restriction>
            </xs:simpleType>
        </xs:attribute>

I added the following schematron code:

XML

<xs:element name="ImageView" maxOccurs="unbounded" minOccurs="1" type="ImageView_Type" >
<xs:annotation>
    <xs:appinfo>
        <sch:pattern name="Co-occurrence constraint on attribute Title" xmlns:sch="http://purl.oclc.org/dsdl/schematron">
        <!--<sch:rule context="ImageView">-->
        <sch:rule context="*[@Attribute1]">
        <sch:assert test="(@Attribute1 = 'XYZ' and @Attribute2 = 'ABC')">If the Attribute1 is "XYZ" then the Attribute2 must be "ABC".</sch:assert>
        </sch:rule>
        </sch:pattern>
    </xs:appinfo>
</xs:annotation>

but still it is not performing the validation , i am using MSXML4 for xml validation.
