This Amendment to CCITT Rec. X.722 | ISO/IEC 10165-4, the Guidelines for Definition of Managed Objects, covers two topics.

One topic of the amendment is the specification of a NO-MODIFY syntax element to the GDMO Package Templates.

The other topic of the amendment is a guidelines extension which describes rules for specifications of management information based on the X.700-Series to evolve to the use of ASN.1:1994 from ASN.1:1990. The guidelines extension provides a common and consistent means to do this, so that product developers are provided with a single way to specify use of ASN.1:1994 in the Recommendations they implement.
