UML25 — Surplus classifier field serialized in Superstructure.xmi

I've encountered one slight problem in the superstructure XMI file of UML2.4.1 .

I've grabbed the ptc/2010-11-18 revision of Superstructure.xmi from here:
http://www.omg.org/spec/UML/2.4.1/

On examining I see that all enumeration literals contain classifier="..." field serialized; e.g.:
> <ownedLiteral xmi:type="uml:EnumerationLiteral"
> xmi:id="Activities-CompleteActivities-ObjectNodeOrderingKind-unordered" name="unordered"
> classifier="Activities-CompleteActivities-ObjectNodeOrderingKind">
There are ~62 such places in Superstructure.xmi (I've not looked into Infrastructure.xmi, but I
think there will also be cases like this)

Classifier metaproperty of EnumerationLiteral metaclass is derived in UML2.4.1 - per Figure 7.13 and
chapter 7.3.17
(EnumerationLiteral::classifier redefines the original InstanceSpecification::classifier, which is
not derived).

Since derived fields are not usually serialized by XMI production rules (unless this is overridden,
which seems not to be the case),
I think these fields should be cleaned out.

This issue has already been resolved by, or no longer applies to, the UML 2.5 Beta 1 specification.
