It highlights the needs aimed to be covered, the various solutions and the rules they must adhere to so
that interoperability can be achieved.
The terms “shall”, “shall not”, “should”, “should not”, “may”, “need not” “can” and “cannot” are to be
interpreted according Annex H of Part 3 of the CEN-CENELEC Internal Regulations .

1 Scope
This document describes:
— the rationale for building customisation supporting business cases that are specific to their business
environment while maintaining organisational and semantic interoperability with the TC 440
specifications;
— the difference between Usage specification and Extension specification;
— a methodology on how to define customisations on:
— BII Transaction specification,
— Business rules,
— Code lists;
— how to claim compliance or conformance to a customisation of a TC 440 specification;
— the connection to the eProcurement Ontology project.
This specification does not describe the detailed process of building an extension.
