BUG#: 9118
TITLE: Add support for CIM_IndicationFilter.SourceNamespaces[] property
DESCRIPTION: Added support for the SourceNamespaces[] property. The values in the SourceNamespaces property and the SourceNamespace property are not additive. If both sourceNamespace and SourceNamespaces are non NULL, the namespace defined in sourceNamespace must also exist in sourceNamespaces.
