[xacml] IIC012: syntax-error or processing-error?

Conformance Test IIC012 is intended to test for the error case in
which a Condition FunctionId uses a function that does not return
a Boolean result.  The <Condition is:

        <Condition FunctionId="urn:oasis:names:tc:xacml:1.0:function:integer-subtract">
            <Apply FunctionId="urn:oasis:names:tc:xacml:1.0:function:integer-one-and-only">
                <SubjectAttributeDesignator
                      AttributeId="urn:oasis:names:tc:xacml:1.0:conformance-test:age"
                      DataType="http://www.w3.org/2001/XMLSchema#integer"/>
            </Apply>
            <Apply FunctionId="urn:oasis:names:tc:xacml:1.0:function:integer-one-and-only">
                <EnvironmentAttributeDesignator
                      AttributeId="urn:oasis:names:tc:xacml:1.0:conformance-test:bart-simpson-age"
                      DataType="http://www.w3.org/2001/XMLSchema#integer"/>
            </Apply>
        </Condition>

Question: should the StatusCode Value from evaluating this Policy
be "urn:...:status:syntax-error" (since it is a type error), or
"urn:...:status:processing-error"?

I'm leaning toward syntax-error.  What do others think?
