Document in which there will be no cross-references (8)
I believe the answer is:
pedigree
'document in which there will be no cross-references' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for pedigree that I've seen before include "High-class" , "Pure-bred animal's line of descent" , "Of animals, recorded line of descent" , "Blood line" , "Record of descent" .)
