I had a question posed to me the other day by another programmer. I remember (a very long time ago) wondering the very same. Why was a browser-side include tag never considered? Or was it?
Specifically with a tag that instructed the browser to include additional HTML from other sources. e.g. <include src="http://server/foo/bar.html">. Many folks will make javascript calls and fill innerHTML to accomplish the same, when the same outside a the javascript engine could be accomplished by the browser.
It would have been painful to have nested <HTML>s <BODY>s (i.e.) but we have to consider that aspect anywhere anyway.

Am I the last person on earth who remembers the (Netscape 4-only)
layerandilayertags?Netscape 4 also allowed the
divtag to have asrcattribute, which accomplished the same thing.Netscape submitted them to the W3C, who chose to not include them—use
iframeinstead.
