This question is out of the jourisdiction of the SGML standard:
it's a question of how we're going to interpret things and display

But, unlike the normal typeset paragraphs where ignoring a newline
here or there is no big deal, the writers of PRE sections want
some assurance as to what the output will look like.

It's on the todo list. I suggested we ignore <p> within <pre>,
but that looks like a bad idea. So now the current thinking,
I believe, is to render it as a line break. This makes those
man pages that end in <p> _and_ newline double space, but
we'll put the onus on the provider to fix that.

I agree (again: this is not an SGML question, but a WWW question).

>>o Is '&lt' ('&lt;' without the semicolon) a valid construct?

Now this is an SGML question, and you're wrong: it's legal.

>>o Can raw <'s and >'s be in a <pre> section?

Again, this is an SGML question, and you're wrong.
Is a < b?
is perfectly valid markup.
