<!--
    This is the bitTorrent 0.1 DTD; a simple XML format for describing
    collections of one or more torrents.

    Namespace = http://xmlns.ezrss.it/0.1/

    This DTD is identified by the PUBLIC and SYSTEM identifiers:

      PUBLIC "-//bitTorrent//DTD Torrent 0.1//EN"
      SYSTEM "http://xmlns.ezrss.it/0.1/dtd/"

    Clients are expected to handle extensions to this specification.
    If you're not parsing it with a reasonable XML parser and coping
    with elements and attributes your client doesn't know about, well,
    your client is broken.
