      <h1>MTOM Policy Assertion 1.0 Namespace: <code>http://www.w3.org/@@@/soap12-mtom-policy</code></h1>
    </div>

    <p>This (<code>http://www.w3.org/@@@/soap12-mtom-policy</code>) is a URI defined in the

    <a href="http://www.w3.org/@@@/soap12-mtom-policy/">MTOM Policy Assertion 1.0</a> @@@(dated) specifications.</p>

    <p>This document describes the MTOM Policy Assertion 1.0 namespace. A <a
    href='soap12-mtom-policy.xhtml'>RDDL version</a> of this document is
    available.</p>

    <h2>Latest XML Schema:</h2>

    <p>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.</p>
      <p>
	<a title="Latest MTOM Policy Assertion 1.0 schema document"
	    href="http://www.w3.org/@@@/soap12-mtom-policy.xsd">http://www.w3.org/@@@/soap12-mtom-policy.xsd</a>

      </p>

    <h2>This dated version of the XML Schema:</h2>

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

      <p>
	<a title="@@@(dated) MTOM Policy Assertion 1.0 schema document"
	   href="http://www.w3.org/@@@/soap12-mtom-policy.xsd">http://www.w3.org/@@@/soap12-mtom-policy.xsd</a>
      </p>

    <h2>Stability of this namespace URI:</h2>

<p>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.</p>
<p>Under this policy, the following are examples of backwards
compatible changes that would not result in assignment of a new XML
namespace URI:</p>
<ul>
<li>

<p>Addition of new global element, attribute, complexType and
simpleType definitions.</p>
</li>
<li>
<p>Addition of new elements or attributes in locations covered by a
previously specified wildcard.</p>

</li>
<li>
<p>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.</p>

</li>
<li>
<p>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.</p>
</li>
</ul>
<!--
    <p>This namespace URI (<code>http://www.w3.org/ns/oap12-mtom-policy</code>) is defined in a <a
    href="http://www.w3.org/Consortium/Process/tr.html#RecsW3C">W3C
    Recommendation</a> and is stable.</p>
