[CSS21] part of section 7.3 incorrectly specific to @media (and not @import)

Media lists in @import rules are defined in section 6.3:
http://www.w3.org/TR/CSS21/cascade.html#at-import
and media lists in @media rules are defined in section 7.2.1:
http://www.w3.org/TR/CSS21/media.html#at-media-rule
both of which refer (not normatively enough, in my opinion, but that's
another issue) to section 7.3:
http://www.w3.org/TR/CSS21/media.html#media-types

However, one of the statements in section 7.3 is specific to @media
rules:

# Unknown media type names must not result in the @media rule being
# ignored. 

This should probably be changed to:

# Unknown media type names must not result in the @media rule or @import
# rule being ignored. 

or be reworded so that it doesn't refer to the type of rule containing
the media types.
