Name relationships in vCard 3.0

What is the relationship between the N: and FN: types. In particular,
there is nothing I can find in the RFC that explicitly requires the
contents of these types to match, and both fields are mandatory. Is
there a reason to allow them to mismatch? If not, the contents of FN:
need to be generated from the contents of N:, or else the contents of
the two types may not match (see below)

	FN:Mr. John Q. Public\, Esq.
	N:Putenesca;Fanny;Mae;Mrs
