prop-145: Single Source for Definitions

This proposal suggests that APNIC use a single definition document to ensure that terms are used and interpreted consistently across APNIC policy documents.

It was looked into RIRs. Some regions do not have specific definition section in Policy documents.

This proposal appears to be straightforward. APNIC understands the importance of
maintaining consistency in the terms and definitions used across all documents.

There are no issues with updating the APNIC Definitions Document (APNIC-080) to
ensure it remains the definitive source of all definitions; however, some
variations in individual documents may be required.

This proposal would not require any system changes, but it would require a
thorough review of all documents.

If this proposal reaches consensus, implementation can be completed within 3
to 6 months.
