RTC The template has an invalid specification of work items and cannot be used.

I have created a work item template(code below) that creates a defect and task record upon completion (works fine)

<?xml version="1.0" encoding="UTF-8"?>
<rtc_cm:WorkItemTemplate xmlns:rtc_cm="http://jazz.net/xmlns/prod/jazz/rtc/cm/1.0/"
    xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="http://purl.org/dc/terms/"
    xmlns:oslc_cm="http://open-services.net/xmlns/cm/1.0/">
    <dc:identifier>com.ibm.team.workitem.template1</dc:identifier>
    <dc:title>Defect with FOO</dc:title>
    <dc:description>This template creates a Defect plus a child work item that can contain protected FOO.
    </dc:description>
    <rtc_cm:workItems>
        <rtc_cm:defect rdf:ID="item0">
            <rtc_cm:filedAgainst rdf:resource="${filedAgainst:Category}" />
            <oslc_cm:severity>severity.literal.l4</oslc_cm:severity>
            <dc:title>Defect Summary Here</dc:title>
        </rtc_cm:defect>
        <rtc_cm:task rdf:ID="item1">
            <rtc_cm:filedAgainst rdf:resource="FOO Access" />
            <dc:description>This item contains FOO.</dc:description>
            <dc:title>FOO Item</dc:title>
            <rtc_cm:com.ibm.team.workitem.linktype.parentworkitem.parent
                rdf:resource="#item0" />
        </rtc_cm:task>
    </rtc_cm:workItems>
</rtc_cm:WorkItemTemplate>

This works fine (creates the defect and the task) yet if I change
<rtc_cm:task rdf:ID="item1">      to        <rtc_cm:anothertype rdf:ID="item1">

I get the error:
"The template has an invalid specification of work items and cannot be used."

I have tried to create the another type as a copy(well mimmic) of OOTB task and or defect types and still seems to complain
