[authors] Another thing to check when reviewing

[Jean Hollis Weber]

When reviewing a chapter, another thing to check is references to 
other parts of the chapter. Occasionally a writer has typed in the 
name of a section instead of using OOo's cross-referencing feature. 
Reviewers should either correct the problem (by converting the 
hard-coded x-ref to an automatic one) or notice if the referenced 
topic is not in the chapter.

I just discovered such an error in a chapter that has recently been 
reviewed by two people, neither of whom reported the problem, although 
there was nothing even remotely like the x-ref'd topic in the chapter. 
I don't expect reviewers to know where missing topics have gone, but I 
do expect them to make a note that the referenced topic isn't there.
