Re: [csswg-drafts] [css-shadow-parts] fully specify the parser for the forwarding micro-syntax

Makes total sense to me but e.g. look at [Lists of floating-point numbers
](https://html.spec.whatwg.org/#lists-of-floating-point-numbers) where the "valid" definition eplicitly rules out whitespace and the parser copes with it. I assumed that the "valid" one was actually specifying the canonical/serialized verison rather than the only valid format (since other examples in the spec are similarly divergent). I'm happy to go either way, any advice appreciated.
