The spec currently says that the expression in dfdl:outputValueCalc must not refer to itself.  I am wondering if that is too restrictive. For example, what if I wanted to apply a simple transformation to the data before it is serialized, example:

<xs:element name="f1" type="xs:string" dfdl:outputValueCalc="{fn:upper-case(.)}" />
