I suggest revisions to simplify the wording:
It is the intent of the W3C XML Protocols Working Group that the MTOM
Policy Assertion 1.0 XML namespace URI will not change 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 contain any non-backwards compatible changes from a
previously published WD, CR or PR draft of the specification, the
namespace URI will be changed.
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 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

*	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.
