-### The `matches` object
-
-A `matches` object contains hints to help automatically detect whether source code corresponds to a feature, such as a list of keywords or a regular expression. A `matches` object may have one of the following properties (in order of preference):
-
-- `keywords`: an array of one or more literal strings that correspond to the feature.
-
-  Examples:
-
-  - In CSS selector features, they can be literal selectors. See [`css.selectors.backdrop`](../css/selectors/backdrop.json)).
-  - In CSS property subfeatures, they can be data type keywords or function keywords. See [`css.properties.transform.3d`](../css/properties/transform.json)).
-
-- `regex_token`: a string containing a regular expression that matches a single token (i.e., text delimited by characters that are excluded from the text to be matched) corresponding to the feature.
-
-  Tests are required for all regular expressions. See [`test-regexes.js`](../tests/test-regexes.js).
-
-  Examples:
-
-  - In CSS property subfeatures, they can be regular expressions that match component value types. See [`css.properties.color.alpha_hexadecimal_notation`](../css/properties/color.json) and corresponding tests.
-
-- `regex_value`: a string containing a regular expression that matches a complete value corresponding to the feature.
-
-  Tests are required for all regular expressions. See [`test-regexes.js`](../tests/test-regexes.js).
-
-  Examples:
-
-  - In CSS property subfeatures, these can be regular expressions that match whole declaration values. See [`css.properties.transform-origin.three_value_syntax`](../css/properties/transform-origin.json) and corresponding tests.
