This is an XML namespace for use as specified in URISpace 1.0.
This namespace name may be reused in any update of the specification which is made for the purpose of clarification or bug fixes. These changes will be minor in that they do not (a) change the meaning or validity of existing documents written using the namespace, or (b) affect the operation of existing software written to process such documents.
