I'm just curious if any popular browser would display this page properly http://www.tarunz.org/~vassilii/html-is-an-sgml-dtd.html I though Moz would, but it disapointed me.
Opera does, but only for XML (i.e. application/xhtml+xml).
I've saved it as .xml, tided it to be well-formed and got: "Your browser (Opera/8.0 (Windows NT 5.1; U; en)) rules! Drop me a line..."
<!DOCTYPE HTML [
<!ENTITY But "">
<!ENTITY your "">
<!ENTITY fine "">
<!ENTITY browser "">
<!ENTITY does "">
<!ENTITY n0t 'Your browser (Opera/8.0 (Windows NT 5.1; U; en)) rules! <a href="mailto:[EMAIL PROTECTED]">Drop</a> me a line...'>
<!ENTITY care "">
