Did somebody already suggest to just use url() and image()?

url(#foo) refers to the element with ID foo in the current document.

Because it's a URL, you can even use Xpointer to refer to elements without IDs. And there is a Community Group[1] that is proposing to extend Xpointer to allow CSS selectors and not only XPath.

And a second advantage: If you can use url(), then you can automatically also use attr(), because attr() can be a URL, too:

    A:local-link:after { content: "(" attr(href, url) ")" }

(And a possible third advantage: If you use url() and attr(), then you can also use the target-text() that GCPM proposes in case you want just the text of the referenced element and not the style.)
