If I may be so nosy, where did this idea come from? It doesn't seem to
have come in as a NOTE, and so far as I know it lacks the usual SGML
ancestry. Glimmerings of it are visible in the XML 1.0 spec (xml:lang and
xml:space), but otherwise it seems to have arrived fully born.
I'd love to know where this one came from... explaining these things
without some kind of story is difficult at best.
