to that code position, and there is no need to replicate this information in the sub-repertoire definition.

At present, a request to ISO/IEC JTC 1/SC 2 (which will be assigned to ISO/IEC SC 2/WG 2) to issue

a collection identifier and enter that into the Annex A of the standard is all that is needed to identify

such a sub-repertoire.

The existing procedure to add a collection identifier is through a "technical amendment" to the

standard, since Annex A is a "normative" annex of the standard. Even though this procedure is more

complex and cumbersome than a simple registration procedure, it can be effectively used to handle the

requests for registration of sub-repertoires of 10646. A request for identifying a sub-repertoire can be

prepared and submitted by a member body, a liaison organization or an individual expert to SC 2, along

with some background information and rationale behind the request.

It is further proposed that the existing "technical amendment" procedure be retained as it gives the

maximum amount of filtering and control of requests for identifying sub-repertoires by ISO at the same

time being able to respond responsibly to legitimate requests.
