    The atom:id is defined as follows:

    The "atom:id" element's content conveys a permanent, globally unique
    identifier for the feed. It MUST NOT change over time, even if the feed is
    relocated. atom:feed elements MAY contain an atom:id element, but MUST NOT
    contain more than one. The content of this element, when present, MUST be a
    URI.
