http://www.w3.org/@@@/soap12-mtom-policyThis (http://www.w3.org/@@@/soap12-mtom-policy) is a URI defined in the
MTOM Policy Assertion 1.0 @@@(dated) specifications.
This document describes the MTOM Policy Assertion 1.0 namespace. A RDDL version of this document is available.
The following URI always points to the latest schema (including errata) for the MTOM Policy Assertion 1.0 namespace. The resource at this location may change as new errata are incorporated.

The following URI points to the schema for the MTOM Policy Assertion 1.0 namespace corresponding to the @@@(dated) specifications.

It is the intent of the W3C XML Protocols Working Group that the MTOM Policy Assertion 1.0 XML namespace URI will not change arbitrarily with each subsequent revision of the corresponding XML Schema documents as the specifications transition through Candidate Recommendation, Proposed Recommendation and Recommendation status. However, should the specifications revert to Working Draft status, and a subsequent revision, published as a WD, CR or PR draft, results in non-backwardly compatible changes from a previously published WD, CR or PR draft of the specification, the namespace URI will be changed accordingly.
Under this policy, the following are examples of backwards compatible changes that would not result in assignment of a new XML namespace URI:
Addition of new global element, attribute, complexType and simpleType 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 vast majority of instances would remain valid.
Modifications to the cardinality of elements (i.e. modifications to minOccurs or maxOccurs attribute value of an element declaration) 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.
