attrib
  : '[' S* IDENT S* [ [ '=' | INCLUDES | DASHMATCH ] S*
    [ IDENT | STRING ] S* ]? ']'
  ;

http://www.w3.org/TR/CSS21/grammar.html#grammar

I think INCLUDES is/represents/can be substituted with "~=" and DASHMATCH
is/represents/can be substituted with "|=" in that grammar/lexical
analysis declaration.

By the way, we have - it appears - only 2 tests with ~= attribute selector:

http://test.csswg.org/suites/css2.1/nightly-unstable/html4/attribute-value-selector-003.htm

http://test.csswg.org/suites/css2.1/nightly-unstable/html4/attribute-004.htm

and test authors refer to it as "partial match selector" or as "value
match in space-separated list" but not as includes attribute selector.

§ 5.8.1 [1] should at least give such selectors a name by which we could
all refer to it in a consistent manner.
