dialog/dialogue element name disambiguation

aria-dialog versus HTML5's dialog Element

  ISSUE: Currently, there is both an HTML5 element named dialog and an
  ARIA role named dialog. A concern has been raised that the use of such
  synonyms could be detrimental. The editor of the HTML5 draft, Ian
  Hickson, has publicly stated that he is willing to change the
  element's name, but also remarked that "dialog" was the best possible
  choice out of the many considered by the WHAT WG, and pondered the
  need for a "dialog box" element in HTML5 itself. [1] It has, therefore,
  been proposed, that the aria role dialog retain the spelling "d i a l
  o g"; that the spelling "d i a l o g" be reserved in HTML5 for the
  concept of a "dialog box", thereby bringing ARIA and HTML5 into
  harmony; and that the HTML5 element currently named "d i a l o g" be
  changed to reflect the correct spelling for the semantic use for which
  the element is intended, "d i a l o g u e", which should be represented
  by a single letter element -- D -- to avoid confusion and unnecessary ]
  code bloat.

ITEM 1. Reasons for Retaining aria-dialog

   1. it is a term known to computer programmers and professionals when
      spelled "dialog"

   2. it is the preferred spelling for this construct in computer
      science

        A. if one uses "dialog" as a search term at the online version
           of the <cite>Mirriam-Webster Dictionary</cite>, the
           Merriam-Webster entry on "dialog" [2] lists "dialogue" as
           the "main entry" [3], with a related entry "dialog box" [4],
           which is a computing, not a semantic, term

   3. aria-dialog already has multiple implementations; HTML5's DIALOG
      element has none;

ITEM 2. Reasons for Changing HTML5's dialog Element to dialogue or D

   1. "dialogue" is the preferred spelling for the semantic meaning of
      the term "dialog" as currently used in the HTML5 draft;

        A. references:
             I. wikipedia entry on "dialog" resolves to "dialogue" [5]
            II. the Merriam-Webster entry on "dialog" [6] lists
                "dialogue" as the "main entry" [7], with a related 
                entry "dialog box" [8]

   2. since there are many different contexts in which D is an 
      appropriate element/container, the HTML5 dialogue element demands
      a role [9] or type attribute , in order to enable differentiation 
      between types of dialogue;

        A. a preliminary list of predefined role or type values for 
           D follows:
              * conversation
              * dialogue (covers theater, film, fiction, where the
                element is used to distinguish dialogue from other types
                of content)
              * transcript
