They're called THEAD and TFOOT because the default direction is
vertical.  But there's nothing to stop you typesetting a table
horizontally with the headings in THEAD down the lefthand side and the
totals in TFOOT down the righthand side: you don't need a TLEFT and
TRIGHT to enable this. The whole point about doing this in SGML is that
the presentation is unconstrained (as far as possible), even if the
implicit semantics betray the origins.

Point taken, but you'd have to approach the W3C and the browser makers
about this. It can probably be fixed in RFC2070 if you ask the authors,
but the only constraints in HTML are purely semantic, not syntactic.
