Of course not.  But it may be *represented* by an element.

No.  This would be a universally available application convention,
like xml:space and xml:lang, not affecting any infoset.

I don't understand this idea.  You mean magic entity references?
The trouble is that "<" is not actually magic, except that
it needs no declaration: it has a definite replacement text.
Something like "&BEL;" would have no legal replacement.

Just so.
