Sylvain,
I agree with Patrick Garies that this is wrong. Whether the border-collapse
model is used or not is, imho, out-of-scope for the spec, but there should
be borders rendered here. Probably what is happening is that your team has
defined rules="all" to be rules="cols" + rules="rows", i.e. defined the
borders to be applied to the rows and columns, rather than applied them to
the cells. Since the separate borders model cannot render borders applied
to rows and columns, they disappear when Gérard sets border-collapse: separate.
It's unfortunate that the separate borders model cannot handle borders on
rows and columns, but at least in the rules="all" case we don't need to be
limited by this problem.
