Section 6.3 specifies an additional 'host' production to the CSS 2.1 grammar,
however that production is naturally not used anywhere in the existing CSS 2.1
grammar. As a result the addition of the rule is meaningless from the point of
view of parsing @host rules in the context of a stylesheet.

For example, it is not clear if or how @host rules can be combined with @media
rules.

Section 6.3 should specify additional amendment (perhaps to the 'stylesheet'
production) to the CSS grammar to clarify where @host rules appear in a
stylesheet.
