Hi Wayne,

No, there's no de facto rule to say what direction the header in the top
left corner covers. It is both directions equally.  To my mind this means
that most tables should use the scope   attribute to ensure that screen
readers are given the requisite information.  However in practice this isn't
going to happen, and while I'm fairly sick of hearing "January December"
when moving into the last column  of a calendar, in most cases the human
will either be able to determine or guess why this happens and not believe
that January is the header for the December cell.  When headers are less
predictable though, it can be a real issue.

      Subject: Question about ambiguous scope
      Is the scope of upper left corner of a table ever 
      unambiguous without a scope attribute? How does a program 
      determine the scope upper left corner in any simple table 
      without a scope attribute?  Are there an HTML semantic 
      rules that says it is column or row header?
      Wow, I never thought about this until this morning.  What 
      a nifty paradox.
