The <<an-b>> type</h3>

The <var>An+B</var> notation was originally defined using a slightly different tokenizer than the rest of CSS,
resulting in a somewhat odd definition when expressed in terms of CSS tokens.
This section describes how to recognize the <var>An+B</var> notation in terms of CSS tokens
(thus defining the <var>&lt;an+b></var> type for CSS grammar purposes),
(thus defining the <<an-b>> type for CSS grammar purposes),
and how to interpret the CSS tokens to obtain values for <var>A</var> and <var>B</var>.

As part of this, rearrange the ordering of the clauses in the "-" step of [=tokenizer/consume a token=]
so that <<CDC-token>>s are recognized as such instead of becoming a ''--'' <<ident-token>>.

* Don't serialize the digit in an <<an+b>> when A is 1 or -1.
* Don't serialize the digit in an <<an-b>> when A is 1 or -1.

* Define all tokens to have a representation.
