Nasty X-Refs

[Whites]

I just spend best part of an afternoon searching for a broken X-ref  
that, IMHO, should never have existed. I'm updating a document that  
has been through many hands (of various degrees of incompetence). As  
always when I inherit a doc, I start a new Book file from scratch and  
add chapters to it bit but bit. This time, however, there existed a  
statement in the Book file .mif  that referenced an earlier  
incarnation of one of the files, using the old filename (one I had  
never linked to, etc) and a paragraph tag that I never used (but that  
the earlier users apparently had).
Anyone know of a utility that can diagnosis a Book to see if it  
contains X-refs to files not in the book and paragraph tags not in  
any of the files??

Any light shed will be appreciated.
