XML Namespace Document for TOSCA Version 2.0

28 October 2020


This document describes the XML namespace name declared in the specification TOSCA Version 2.0, CSD03:

Namespace URI Versioning Policy

It is the intent of the OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA) TC that XML namespace names identified by URI references will not change arbitrarily with each subsequent revision of the corresponding WSDL or XML Schema documents but rather change only when a subsequent revision, published in conjunction with a Committee Specification Draft, results in non-backwardly compatible changes from a previously published Committee Specification Draft.

Under this policy, the following are examples of backwards compatible changes that would not result in assignment of a new namespace URI:
