Explain use of global elements, namespaces, and xml metadata models (xhtml, docbook, resource description framework (rdf), and really simple syndication (rss).

Global elements are elements that are children of a schema element

They are root elements and used to tag or label the programming schema or structure.

Global Elements must be declared before it's used.

Namespace:

Codes must be grouped or organised into logical groups. This can be achieved using namespaces because it so prevent name collision especially when there are lots of libraries in the code.
