have evolved independently over time. This memo provides the definitive overview of the (currently) relevant documentation.
As such, it acts as a definition of the core standard for URIs, incorporating existing standards documents by reference.

- The Pros and Cons of XML
Ronald Schmelzer (NEW 07. August)
A lot has been written, said, and discussed about the Extensible Markup Language (XML). As a result, there is a lot of confusion
and chaos regarding exactly what XML means. Is it a language, document, modeling tool, e-Business application, or none of
the above? What exactly does XML have to offer? Why does it matter? Furthermore, what does XML bring to the table that other
languages, documents, tools, and applications have not been able to do in myriad other ways?
