> Why can't HTML alone do includes?

A quick Chrome Extension Polyfill for all those who are curious.

Any reason that the tag isn't a void element, i.e. that it must be

    <include src="path/to/fragment.html"></include>

instead of

    <include src="path/to/fragment.html"/>

?

So visitors need a chrome extension?

Chrome extension seems like the wrong way to do this. Should be a web component or just a simple JS file.
