A Namespace is used for to uniquely identify set of names of objects but these names have different-2 behaviors to reduced the ambiguity of codes or we can say more names from other similar names of different objects, groups or the Namespace in general. By Namespace possible to distinguish objects with similar names but different origins. In XML file number of Namespaces of objects are stored which are uniquely find by unique Namespace for unique attributes. Namespace is primarily used in programming languages where the same name may be used for different objects. It is created to group together those names that might be repeated elsewhere within the same or interlinked programs, objects and elements. Each of the names within that namespace is only related/linked to that Namespace
