# [NTG-context] cross references to chapters in a book

Hmm… although I got your example to work after some tweaking (changing \samplefile to {input and placing knuth.tex and zapf.tex in the same folder as the test file), I could not reproduce this with my book. I want to get "chapter 4" but keep getting "chapter 4.0".

Is this because I am using MkII with XeTeX?

I’ve already figured out how to refer to pages (using “\at[REFERENCE]”), but how is this done with chapters? I’m apparently too simple-minded to understand the manual (and I don’t understand the differences between \reference, \textreference, \in, \about).
