A series of #x20, #x9, #xD, #xA characters can be normalized into one 
#x20 character, #xA0 characters cannot. So for test 3.12 I think it's 
good not to count #xA0 as (extraneous) white space.

> - What happen with CSS2? It's implicitly allowed as there is no test that fail when using CSS2 properties, even referenced at 3.20. Should these properties also be checked? If so, other test may also be reviewed as they are affected (e.g. see comment #6 at [2])

Test 3.4 fails for content that is not valid CSS with validity being 
defined as conforming to the CSS 1 grammar (syntax).

Test 3.21 seems to use the phrase "valid CSS 1" in a sense that is not 
just grammar conformance.

So right now, CSS 2 that conforms to the CSS 1 grammar passes 3.4, but 
you'll get a lot of warnings, because the grammar does not define 
properties and values (3.21) :-)

Additionally,

   @import "foo.css" handheld;

would fail 3.4 because of the media type, which is not part of the CSS 1 
grammar, while the rule should be considered when collecting the 
"Included Resources" (2.3.6).
