That is what I was aiming at with relatived units. As it happens, pixels  
are scalable too, and most decent modern systems allow you to scale them.  
The problem, as Joe Clark recently pointed out, is that real problems can  
arise if you just zoom on layouts. Browsers like Opera, which have had  
this feature for years, actually do some reasonably intelligent  
decision-making about what to zoom and what not to, rather than simply  
scaling the size of the units.

It would be nice to have a simple erratum in WCAG 1, excluding pixels as  
units that should be used. And to have a more generally thorough approach  
in WCAG 2.

I remind you that comments about wcag should be made to the working group,  
who have set up mailing lists especially for that purpose. See
