Just like the .NET namespaces, it is designed to allow you to clearly identify objects and avoid name conflicts.

E.g. you can have a Person in the http://mycompany.com/schemas/Internal XML namespace, and also another type Person in http://mycompany.com/schemas/ERP - and those two will not conflict on their name.

See this great article here The XML Files - Understanding XML Namespaces which explains it in much greater detail and much better than I do.
