Given that the standard has been around for a number of years, and the
list of implementations keeps growing, I think you can assume that
this question has been answered.

Oh...definitely. I don't dispute that there was general belief that
this would be the case. But the real world has impinged, and there is
really no reason for such a limitation.

Again, you are right in that this is what is stated. But
architecturally it makes no sense to impose such a limitation,
especially since real implementations prove that it is an unnecessary
constraint.

That's right. I thought we'd already agreed on that.

No-one said that. The illustration was in the context of 'depends what
you mean by an XML application'.

I thought we had agreed that. :) But I'm happy to re-agree.

All the best,
