In plain English the content model of the CgPoints element is any
number of CgPoint elements, followed by any number of CgPoints
elements, followed by any number of Feature elements.

Now if we look at your XML fragment, we can see that it does not conform
to the above content model: you have two CgPoint elements following a
CgPoints element. If you move the last two CgPoint elements before
CgPoints, then everything should validate Ok.
