In 5.2.2 Closure Tables, there is an XML snippet showing how the <Closure>element maps the level onto a <Table>. I don't see the ending </Level> for the Level named "Employee ID". I am assuming that the Property tags reference the Level, not the Hierarchy, so the tag seems like it should go just before </Hierarchy>.
On a side note, I would like to find some guidance as to how Mondrian uses the technical key fields generate in Kettle's Dimension Lookup/Update step. Is this somewhere in the documents.
