Method of providing unique elements and attributes in an XML document
XML namespaces are used for providing uniquely named elements and attributes in an XML document. They are defined in a W3C recommendation.[1][2] An XML instance may contain element or attribute names from more than one XML vocabulary. If each vocabulary is given a namespace, the ambiguity between identically named elements or attributes can be resolved.
A simple example would be to consider an XML instance that contained references to a customer and an ordered product. Both the customer element and the product element could have a child element named id. References to the id element would therefore be ambiguous; placing them in different namespaces would remove the ambiguity.
