if IE @import in stylesheet

Hi

Could somebody please tell me if it is possible to import an external stylesheet into another external stylesheet, but only if the browser is IE?

Please note.  I am not asking how to do this in the head of an html file, but how to do it in the stylesheet itself.

Thanks

Something like

<!--[if IE]>
@import "/css/iewin.css";
<![endif]-->

body {}
etc...
