Add SVG `use` with external reference

[alejandroiglesias]

It would be good to add this feature since the browser support is variable (no IE or old Safari).
How it looks like:

<!-- Reference IN THIS SAME DOCUMENT -->
<svg>
  <use xlink:href="#icon-1"></use>
</svg>

<!-- EXTERNAL reference -->
<svg>
  <use xlink:href="sprite.svg#icon-1"></use>
</svg>

Edge 12 also doesn't support this, according to the svg4everybody polyfill

Also xlink deprecation: https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/xlink:href.

+1. I just tried to look this up because of the xlink:href deprecation :)

Looks like this is now covered by MDN data:
https://caniuse.com/mdn-svg_elements_use_xlink_href
https://caniuse.com/mdn-svg_elements_use_href

(via mdn/browser-compat-data#1419)

I think the MDN data is just for support xlink:href, not specific to external references

I thought <use xlink:href> and <use href> was all this issue was about. I'm not seeing any examples of other forms of external references.

MDN’s content for SVG is woefully incomplete. Don’t expect it to be as comprehensive or up-to-date for SVG as it is for HTML, CSS, and JS.
