ACS Configuration Web Services: query problem

Question

I don't know if this is the correct place to ask, I couldn't find a specific ACS category.
I am trying to do a query, according to chapter 4 in the ACS 5.3 Secure Access Control System 5.3
My URL is:
https://myurl/Rest/Identity/IdentityGroup/op/query
doing a PUT request
have a header of Content-Type: application/xml
and my payload is:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:query xmlns:ns2="query.rest.mgmt.acs.nm.cisco.com">
    <criteria xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:SimpleFilter">
        <simpleFilter>
            <propertyName>identityGroup</propertyName>
            <operation>EQUALS</operation>
            <value>AllGroups:Migrated_Group:NetworkEngineer</value>
        </simpleFilter>
    </criteria>
    <numberofItemsInPage>100</numberofItemsInPage>
    <startPageNumber>1</startPageNumber>
</ns2:query>
I get back:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><ns2:restResult xmlns:ns2="common.rest.mgmt.acs.nm.cisco.com"><errorCode>61000</errorCode><httpCode>400</httpCode><moreErrInfo>XML Parsing Error:  Unable to create an instance of com.cisco.nm.acs.mgmt.rest.query.AbstractFilter. </moreErrInfo><operationType>NOT_AVAILABLE</operationType><resourceType>NOT_AVAILABLE</resourceType><status>BAD_REQUEST</status></ns2:restResult>
and a 400 Bad Request.
Can you tell me what I am doing wrong?
All I want to do is get a list of users who belong to that group?

I learned that a simple filter does not need the ... bracketiing, so this would work:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:SimpleFilter">
            identityGroup
            EQUALS
            AllGroups:Migrated_Group:NetworkEngineer
    100
    1
