Hi Kenny,

I'm trying to evaluate this for CSS21 errata; if you wouldn't mind 
assisting me, please could you comment on why you think the behaviour of 
the UAs doesn't match the spec, quoting the part of the spec which you 
think governs this.  (You've stated why a particular rule in the spec is 
not relevant to the situation.)

Thanks,
Anton Prowse
