<p>Elements can have <i>attributes</i>, which are name-value pairs. Order of attributes is not significant; an element&#8217;s attributes form an unordered set of keys and values, like a Python dictionary. Attributes are listed within the start tag of an element. <i>Attribute names</i> can not be repeated on the same element (although they can appear on different elements). <i>Attribute values</i> must be quoted.

<p>As far as an XML parser is concerned, the previous two XML documents are <em>identical</em>. Namespace + element name = XML identity. Prefixes only exist to refer to namespaces, so the actual prefix name (<code>atom:</code>) is irrelevant. The namespaces match, the element names match, the attributes (or lack of attributes) match, and each element&#8217;s text content matches, therefore the XML documents are the same.
