  @QName: Markup|Atom
  @enFN:
    Atom DOM
  @enDesc:
    The <DFN::Atom DOM> is a language and platform independent
    programming language interface to Atom 1.0 documents
    built on the W3C Document Object Model (DOM).  It defines
    a number of interfaces that provide convenience
    methods and attributes to process Atom 1.0 documents.

      {TODO::
        - Move descriptions below to somewhere.

        - Formal definition for <IF::StaticNodeList> (reference
          to Selectors API?) is necessary.
      }

    Some attributes are defined to contain a <IF::StaticNodeList>.
    Multiple invocations for such an attribute don't have
    to return exactly same object, even if no changes are made
    on the underlying DOM structure.

      {NOTE::
        The equality of <IF::StaticNodeList> objects as per
        the <M::Node.isEqualNode> method, however, is
        preserved as long as the underlying DOM structure
        and the configuration parameters are not changed.
      }

    Methods and attributes defined in this module does <EM::not>
    support <IF::tx|EntityReference>s; for example, an element
    node that is a child node of an entity reference node
    that is a child node of another element node is <EM::not> considered
    as a child element node of the other element node.  As a
    result, applications written using this module might ignore
    parts of Atom documents unless they configures their XML
    parser not to expose entity references in the result DOM tree.
