Hi David

It is written at the start of Annex C of X.521, as copied below

> Upper bounds
> (This annex does not form an integral part of this Recommendation | International Standard)
> This annex includes all of the suggested upper bound value constraints used in these Directory Specifications, in the form of the ASN.1 module UpperBounds.

> UpperBounds {joint-iso-itu-t ds(5) module(1) upperBounds(10) 5}
> DEFINITIONS ::=
> BEGIN
