Section 7.2.4.1 says:

(+) If the cause location is 'user' than the 6xx code could be given 
rather than the 4xx code (i.e., 403 becomes 603)

It should say:

(+) If the cause location is 'user', then the 6xx code could be given 
rather than the 4xx code (i.e., 403 becomes 603)

Notes:

"Than" is used for comparisons. "Then" is used to denote something follows in sequence.
