Example doesn't match page

### Type of issue

Missing information

### Description

The page for `XpsDocument.CreateXpsDocumentWriter` claims to have a sample for that method: "The following example shows how to use the CreateXpsDocumentWriter method in order to write an XpsDocument"

... but the sample is `WordXmlSerializer.SaveToFile(fileName, flowDocument.ContentStart, flowDocument.ContentEnd)` which appears to be completely irrelevant.

Possibly just some incorrect linking?
