W3c markup validator, extended version, choosg outline will show if there are missing <hx>. I think we need to ask the same, because this is also a markup requirement.

    Oggetto: [techs] Review of tests 37, 38, 39, 40, 41 - Header nesting
    
    
    I propose that we reject tests 37, 38, 39, 40, and 41 [1].  As written, they would not allow the following:
    h1
      h2
       h3
         h4
        h3
         h4
      h2
    etc.
    
    The HTML specification says:
    "Some people consider skipping heading levels to be bad practice. They accept H1 H2 H1 while they do not accept H1 H3 H1 since the heading level H2 is skipped."
    
    Therefore, we could create a test of the form, "hn+2 shouldn't follow hn" e.g., h3 shouldn't follow h1.  This maps to the HTML Technique, "Do not user headers solely for visual effects." <http://www.w3.org/WAI/GL/WCAG20/WD-WCAG20-HTML-TECHS-20050211/#hx-misuse>
    
    A more important test is the order in which the headings will be navigated and the content associated with each, ala the thread on IG: <http://lists.w3.org/Archives/Public/w3c-wai-ig/2005JanMar/0369.html>
    UAWG has a test for this at: 
    <http://www.w3.org/WAI/UA/TS/html401/cp0909/0909-HEADINGS.html> 
    Do we need a similar test?
