Yes, and that makes RE after elements significant in _all_ mixed content, and insignificant outside it. >Or is proposal 3 "when parsing without a DTD treat all whitespace as >significant" and live with the fact that the parse tree is SGML >incompatible.

Not for element content, but that compatiblity is impossible since element content cannot be distinguished from mixed content without a DTD, in any case. And yes, it does throw out pretty-printing (or require some explicit notification from the user as to the presence of such pretty-printing. -- David I am not a number.
