Hi again,

Just in case... I completely agree with you in the advantages and need 
of good semantics. What I am discussing here is if HTML semantics are 
the *only* way of conveying the visual information in a 
"programmatically determinable" way, which is quite different from 
saying "semantics are not useful".

I also think that it's impossible to convey every visual aspect of a 
design to everyone, but it doesn't imply not tring it <smile>


Jonathan and the semantics:
