No example or hint on how to access the `parameter` argument of `Frame.Navigate`

Whilst looking at how to pass identifiable information to the data context of another page, I read the documentation for Frame.Navigate. It is explained well in which cases to use only value types. Unfortunately all the examples show the parameter argument set to null and there is no indication of how the new page in the frame should access this parameter.
