exporting a form:form element to ODF 1.2 yields an invalid file:

/tmp/p_.odp/content.xml[85,193]:Error:element "form:form" is missing "type"
attribute

<form:form form:name="Standard" form:apply-filter="true"
form:command-type="table"
form:control-implementation="ooo:com.sun.star.form.component.Form"
office:target-frame="" xlink:href="">

ODF 1.2 cd04 schema:

<define name="form-form-attlist" combine="interleave">
    <optional>
		<attribute name="xlink:type">
			<value>simple</value>
		</attribute>
        <attribute name="xlink:href">
            <ref name="anyURI"/>
        </attribute>
        <optional>
            <attribute name="xlink:actuate">
                <value>onRequest</value>
            </attribute>
        </optional>
    </optional>
</define>

this seems to have changed from ODF 1.1, where the xlink:type was optional:

<define name="form-form-attlist" combine="interleave">
    <optional>
        <attribute name="xlink:href">
            <ref name="anyURI"/>
        </attribute>
        <optional>
            <attribute name="xlink:type" a:defaultValue="simple">
                <value>simple</value>
            </attribute>
        </optional>
        <optional>
            <attribute name="xlink:actuate" a:defaultValue="onRequest">
                <value>onRequest</value>
            </attribute>
        </optional>
    </optional>
</define>
