what is the point claiming the market has spoken, when most authors
and authoring tools don't provide or promote the use of LONGDESC,
the summary attribute for TABLE, and other accessibility oriented
markup?
that is the point of the Web Accessibility Initiative at the W3C -- to
provide means for making markup as accessible as possible... the
point is EQUAL ACCESS not market share... the argument that the
market doesn't support accessible markup is, well, a word i
probably shouldn't use in a public forum -- the so-called market
for which accessibility oriented markup exists is a fraction of the
overall market, but that shouldn't make our right to equal access
dependent upon market forces... who would have thought, 25 years
ago, that there would be curb-cuts on most street corners and
ramps at most public accomodations? the argument was made then
that it is too much of an economic outlay to justify the small numbers
of those it would help -- and then people using strollers and shopping
carts started to use them, and i doubt if the teenagers skateboarding
down the ramp at my local bank know why there is a ramp there, other
than for their skateboarding pleasure...
markup isn't and shouldn't be a popularity contest -- i'm sure that the
number of CENTER elements on the web outnumbers the uses of
LONGDESC, but a need should NOT be trumped by a perceived rejection
of accessibility oriented markup by the market...
the lack of market share argument simply doesn't hold water when
discussing accessibility and usability concerns,
the market has NOT spoken; it has simply ignored the needs of those of
us who couldn't use today's web without the accessibility features added
to HTML 4.01
