Checking if a css loads an external file

I am building a tool to minify and compile CSS files on-demand. The files can be in different folders, and I need them to be called from their original folder if they are referring to an external file (image, other css, font maybe?).

I wonder which strings I should look for. I only see url( and @import, but am pretty sure I am missing some.

I can think of proprietary CSS: behavior which loads .htc (.js on some servers) for that browser. Also exists as -ms-behavior.
EDIT: oops, behavior will use url() too, not behavior() as I previously wrote... My mistake. Ex: 

.ie67 * {
  behavior: url('htc/boxsizing.htc');
}

I don't think that filter / -ms-filter can load an external resource; it'll rather apply to images and such (somebody correct me if I'm wrong).

In CSS2.1, external resources are URIs so except @import (that must appear before anything else), I think your list is complete.
