We need to develop wcag that are for *all* disabilities, and not be vendor-specific. If it's a Jaws problem, ask to fix it to them, and not that w3c should fix wcag guidelines.
(as for valid code...)

    I agree that Jaws is far from perfect, especially considering that
    every so called improved new version of this same program seems
    to change the way it behaves with web content, and as such causes
    problems, for 
    Real people etc.
    
    However, in an example where you have an hx element above a table, then
    a caption
    in a table, What is inherently wrong with Jaws doing something like
    moving to the
    table (thus skipping the hx) when the user presses t?  h/shift-h in jaws
    moves
    Between the headings, t/shift-t moves between the tables.  Why should
    jaws consider
    An hx to be any part of the table just because it appears above the
    table?
    For all we know, the hx could be a section heading in the page that just
    happens to be
    followed by a table.
    
    If we want to suggest that an hx just above a table is suficient to
    actually link  that
    Table to that hx as explicitly as, for example, label with form control,
    then we are
    starting to expect user agents and assistive technologies to make
    decision about the linkages
    Between different things on a page due to nothing more than screen or
    code proximity.  I hope
    People can see the problems inherent in this.
    
    So how can you link a table to a header that is above it... Is there a
    for/id linkage that can be
    made?  No... So my example shows the inclusion of an hx inside the
    caption.... Which is not
    Given just for jaws compatibility, but because it seems to be a sensible
    way to resolve
    The linkage issue in an explicit way in the code... Which is what we are
    seeking.
    
    So in the example where the hx is above the table with caption, Jaws is
    probably not really
    Doing the wrong thing.  That's not to say that Jaws never does the wrong
    thing by the way.
