• http://docs.oasis-open.org/ws-sx/ws-trust/200802

Namespace URI Versioning Policy

It is the intent of the OASIS Web Services Secure Exchange (WS-SX) 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:

• addition of new global element, attribute, complexType and simpleType definitions
• addition of new operations within a WSDL portType or binding (along with the corresponding schema, message and part definitions)
• addition of new elements or attributes in locations covered by a previously specified wildcard
• modifications to the pattern facet of a type definition for which the value-space of the previous definition remains valid or for which the value-space of the preponderance of instance would remain valid
• modifications to the cardinality of elements for which the value-space of possible instance documents conformant to the previous revision of the schema would still be valid with regards to the revised cardinality rule
