Take this example:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd">
<title>test</title>
<p>...
The <p> closes the implicite head and opens the implicite body since p
doesn't appear in the content model definition of the head element. Same
goes for hr and br, they cannot contain PCDATA so they are closed and
both '>' appear as PCDATA content of the body element in your example.
The document could have been written as
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd">
<html>
<head><title>test</title></head><body><br>><hr>></body>
</html>
That's just how SGML works...
