xml Getting started with xml Namespaces
Example
Element and attribute names live in namespaces that are URIs. Namespaces are bound to prefixes that are used in the actual element and attribute names, which are called QNames.
This document binds a namespace to the prefix prefix and defines a default namespace, bound with the absence of prefix.
<?xml version="1.0"?>
<document
xmlns="http://www.example.com/default-namespace"
xmlns:prefix="http://www.example.com/another-namespace">
<prefix:element/>
</document>
