3.2.4.1.11 CIM XML Namespace
The WS-CIM Mapping Specification defines the CIM XML namespace as http://schemas.dmtf.org/wbem/wscim/1/common, as specified in [DMTF-DSP0230] section 5.3.
Web Services Management Protocol Extensions for Windows Server 2003 operating system clients MUST use http://schemas.dmtf.org/wsman/2005/06/base as the Common Information Model (CIM) namespace instead of http://schemas.dmtf.org/wbem/wscim/1/common.
Note XML namespaces are to be treated as identifiers, and they do not point to any location on the web.
