Abstract
This document defines a new media type for the XML Shareable Playlist
Format (XSPF, pronounced like "spiff"). XSPF allows playlists to be
exchanged between different software, across networks and across
administrative boundaries. A media type registration enhances
shareability.
An XSPF playlist describes a sequence of objects to be rendered in
time. Objects might be audio, video, text, playlists, or any other
media type with an inherent duration. The function of an XSPF
document is to identify the objects and communicate their order.

3. Security considerations
The XML-based media type being registered has all of the security
considerations described in [RFC3023] plus additional
considerations.
Playlist authors who publish documents containing local filesystem
paths should take care to not reveal confidential information
contained in those strings.
The registration does not employ active content.
