Test cases: assigning external CSS to an HTML document with the @import rule in a style element. There are test cases with single or double quotes, with or without the url() syntax. The @import element may have a media descriptor. E.g. (CSS):
@import 'css/import_sq_all.css' all;
See the HTML 4.01 Specification for more information on the style element. See the CSS Level 2 Specification for more information on the @import rule and recognized media types.
