It is how a conformant user agent _does_ behave, as section 3.2 requires 
that "A user agent that renders a document with associated style sheets 
must [...] render the document according to the media-specific 
requirements set forth in this specification".

As previously mentioned, the specification is written so as to define the 
processing model, a description of how an implementation of CSS acts. It 
would thus be inappropriate to litter the specification with RFC2119 
terms, especially since it is unclear how the specification could be 
phrased if that kind of conformance model was adopted (the 8.3.1 section 
being a canonical example of something that would be nigh on impossible 
to specify in that way).

Please let us know if this satisfies your request,
