[css-selectors-4] Use actual types in nth pseudo class selectors #9494
Description
The syntax for nth pseudo class selectors currently use a simplified syntax which later references actual types in the prose. It would be simpler and better for tooling which parses this data to use the actual types.
For example:
:nth-child(An+B [of S]? )
Would be represented as:
:nth-child(<an-b> [of <complex-real-selector-list>]? )
If this is acceptable I'd be happy to supply a patch.
