Tangentially related: specs that aren't defining the core grammar
shouldn't do lexical scanners anyway.  We know that the Appendix G
grammar is broken, in that it doesn't even parse all valid *2.1*
content, so we shouldn't even pretend that people actually use it.  In
practice implementations use some approximation of the Chapter 4
grammar, plus a parser that consumes the tokens.

In other words, MQ should just say that it accepts a <resolution>
there, and be done.

As part of my revival of Syntax, I'll attempt to add grammar tokens
that should make the definitions of at-rules resemble the definitions
of property values.
