 3. Prop renamed: `nestingOperator` -> `combinator`. A proper name according to CSS spec was chosen.
 4. Prop renamed: `rule` -> `nestedRule`. A proper name to indicate nesting was chosen.
 5. Prop changed: `tagName: string` -> `items: [TagName | WildcardTag, ...]`. Using explicit distinction between
    TagName (i.e. `div`) and WildcardTag (`*`), because tag name can also be `*` if escaped properly (`\*`).
-6. Prop changed: `attrs` -> `attributes`. Attribute type was changed, see below.
-7. Prop changed: `pseudos` -> `pseudoClasses`. There are pseudo-elements and pseudo-classes, now they are separated
