Before discussing XML namespaces, it is useful to discuss namespaces in general. In this FAQ, we will refer to such namespaces as traditional namespaces. We will refer to XML namespaces as XML namespaces. The word namespace can refer to either a traditional namespace or an XML namespace, depending on context, but will generally refer to an XML namespace. A traditional namespace is a set of zero or more names, each of which must be unique within the namespace and constructed according to the rules (if any) of the namespace. For example, the names of element types in an XML document inhabit a traditional namespace, as do the names of tables in a relational database and the names of class variables in a Java class. Traditional namespaces also occur outside the field of computer science — for example, the names of people could be thought to inhabit a traditional namespace, as could the names of species.
