Does Daffodil support the XPath "to" operator?

[Roger L Costello]

In an inputValueCalc I want to have this:

if (../BitCode = (12 to 71)) then 'UNDEFINED'

See below. From my testing, it appears that Daffodil does not support the "to" 
operator. Is that correct? Is there a workaround?

<xs:element name="test">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="BitCode" type="unsignedint5"/>
            <xs:element name="Meaning" type="xs:string"
                dfdl:inputValueCalc="{
                if (../BitCode eq 0) then 'A' 
                else if (../BitCode eq 1) then 'B'
                ...
                else if (../BitCode = (12 to 71)) then 'UNDEFINED'  
                else fn:error('invalid value for test')                         
}"
            />
        </xs:sequence>
    </xs:complexType>
</xs:element>
