Re: include in html

SGML has had an include facility since its standardization.  HTML
decided not to include this facility, but if client-side inclusion is
desired, it's the way to go.  XML uses this facility.  It would look
something like:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" [
<!ENTITY headnav SYSTEM "header.html">
<!ENTITY footnav SYSTEM "footer.html">
]>
<html>
<title>Entity example</title>
<body>
&headnav;

<p>This is an example of declaring and referring to entities.</p>

&footnav;
</body>
</html>

It's a bit indirect, in that you have to first declare and then
reference the entities, which makes single-use entities a bit more
complicated than they need to be.  But browsers will be supporting
this for XML anyway, so we might as well use it in HTML.
