Assuming "jdftyp" is a namespace prefix for your target namespace, this
should do what you say (define a list that contains only enumerated
values). What's wrong with this first version?

Have you defined a "NMTOKEN" type in your target namespace, or shouldn't
it be :
<xs:simpleType name="ePartKeysList_">
<xs:list itemType="xs:NMTOKEN"/>
</xs:simpleType>
???

Here, you're defining a list type and restrict the result to be one of
the values in the enumeration. That's fine, but your resulting type is
not really a list any longer.

That just says that the values must be either PartVersion, Separation,
SheetName or Side which is what I mean by "your resulting type is not
really a list any longer" :) ...
