There might be thousands of telephone numbers of 545-321.
No information exists to tell others what the actual data means, its order, or how to parse (read) it in other projects.
For example, take the following XML files, both of which describe some data: The first file specifies genres of movies, while the second specifies different types of camera film.
But, as the consumers of these files, how can we differentiate between them? An XML namespace allows us to qualify an element in the same way as telephone area codes qualify phone numbers.
While an XML file might conform to the XML specification, it might not be a valid form of a particular dialect.
An XML schema lets you verify that certain elements are present, while making sure that the values presented are of the correct type.
