Overview

Provides support for reading and writing simple extensions as defined by the Atom Syndication Format.

A Simple extension is an element from a non-atom namespace that has no attributes and only contains text content. It is interpreted as a key-value pair when the namespace and the localname of the extension make up the key. Since in XML you can have many instances of an element, the values are represented as an array of strings, so to manipulate the values manipulate the array returned by [ns, localname].
