UML14 — Confusion regarding XMI for use of stereotypes

I've been looking at Figure 458 and can't quite get it, but don't know if
it's an issue -the problem I have is that the instance model seems to mix
meta-levels; we have an instance of the UML (meta) class, Class and an
instance of the user stereotype(class) Clock - yet on the diagram this jump
in metalevels is not mentioned. I can't see how this can be the true
Instance model. Could someone provide me with the XMI fragment that this
figure is intended to produce - I think that this would give me more of a
clue about what's going on.
