The IQ Namespaces

The namespaces that qualify attachments to <iq/> elements are many and varied. After all, you could say that the raison d’etre of this request/response mechanism is to exchange structured information—and what better way to define that information than with namespaces?

This section looks briefly at each of the IQ namespaces in turn. Some of them will be covered in more detail in later chapters, as they will be used in examples that appear later in the book.
