Ok, here it is. I’ve attached a text file for a first draft.

The actual parser is not there yet, but I have all the boilerplate 
around it, including a well-defined input and output.

I don’t like the name, but I think that a well-defined concept like 
"regrouped tokens" can be useful for css3-syntax’s interactions with 
selectors, property values and unparsed at-rules.

Perhaps more interesting: I have a parser for :nth-child() and friends 
based on css3-syntax tokens. It’s verbose, it’s not pretty, but I think 
it covers all the cases.

This obviously needs formatting and cross-references, but I’m not 
familiar with the usual spec editing tools.

Any feedback at this point?

Thanks,
