Actually, it has been mentioned, by Paul Prescod, I think.
Doesn't your rule forbidding white space in element content
amount to the same thing to a DTD-less XML parser? It won't
know where data isn't allowed.

I toyed with the idea myself for a while -- figuring we'd
just leave it to the application (through style sheets or
whatever) to ignore those SSEPs it wasn't interested in.
When I realized I had just invented a new kind of comment,
I got badly frightened by the implications.
