Well... both the (shaky, creaky) Mozilla pre-release and the (shaky,
creaky) IE5 developer beta are starting to be able to do this...
so while your statement is correct today, with any luck, this will not
be the case in 6 months.
Having said that, not everyone is going to snap up the V5 browsers, thus
the necessity for HTML information delivery is with us for the forseeable
future. -Tim
