Is it possible to configure the Namespace bindings in cluster level. I have implemented in the cell level. Please do needful help as soon as possible. This is the code i am using now

cellName = AdminControl.getCell()
cell = AdminConfig.getid("/Cell:"+ cellName +"/")
attrs = []
attrs.append( [ 'name', bindIdentifier ] )
attrs.append( [ 'nameInNameSpace', nameinNameSpace ] )
attrs.append( [ 'stringToBind', value ] )
AdminConfig.create("StringNameSpaceBinding",cell,attrs)
Advance Thanks
