XMI12 — Production by Package Extent Example in 00-12-05

I was reading document 00-11-02, i.e. the XMI 1.1 specs, and I was a bit confused with the example of production by Package Extent on page 5-12.

Should the line which says, "Similarly, the second Node in the NodeClass extent..." actually say, "...the second Net in the NetClass extent... "???

There is no reference to PDT, one of the XMI.field values of the second Net object. Also, there seems to be no reference to NodeZ in the same XML, although NodeW is referenced again.

Are these typos??? Sorry for nitpicking
