Incomplete CSS2 grammar specification?

Hi

The CSS2 grammar specification defines the following production:

media
 : MEDIA_SYM S* medium [ ',' S* medium ]* '{' S* ruleset* '}' S*
 ;

Yet my understanding from the spec is that "@media" can also contain "at
keywords", as demonstrated in the HTML 4.0 sample style sheet (fragment):

@media print {
 @page         { margin: 10% }
 H1, H2, H3,
 H4, H5, H6    { page-break-after: avoid; page-break-inside: avoid }
 BLOCKQUOTE,
 PRE           { page-break-inside: avoid }
 UL, OL, DL    { page-break-before: avoid }
}

So I'm assuming the grammar is incomplete, or am I missing something?

Regards,
David
