That is the way I have been doing it with my Cappuccino/Yade/PSC_EDB

My NXP/Yade/PSC_EDB system, at least for now, will also do it like this. 

If you have only a few document instances it works fine. If you have
of them you probably will get into troubles (for the reason already
pointed out by others)

I think, at least for XML, we don't want to use PIs too often.

Maybe as a fallbak if other asscociation mechanisms failed....

Hmm, I think I would like that.

Do I understand correct that you want to include the style into the
actual document instance ? Would work of course, but I guess only
if we assume that DSSSL is the only style-spec. mechanism.
Of course I would support that ;-) No, to be serious, I think
we should separate style and instance as much as we can.


I do also think the idea with the mime header is worth a try.
